It   assumes a basic knowledge of the Internet and networking.   This information is intended to help new or expanding networks   understand and follow the Internet administrative procedures, and to   provide assistance in filling out the various templates and   registration forms.Appendix D is a glossary of acronyms.Wenzel, et al.               Informational                      [Page 2]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000Checklist   This document will explain the following procedures:   o  Determine your organization type and current status.   o  Determine your administrative and technical contacts.   o  Determine your budget (and chargeback system) and choice of      carriers.   o  Determine to whom you will connect.   o  Predict your current and projected address space needs.   o  Set-up your system to connect.   o  Request and register your address space allocation.   o  Request and register an autonomous system number, if needed.   o  Register with a routing database, if needed.   o  Register your country's domain name, if needed.   o  Request and register your IN-ADDR.ARPA domain name, if needed.Prerequisites   This document assumes that you have examined different alternatives   for physical connectivity and will assist you in navigating the   Internet infrastructure so that you can use that connectivity. In   choosing your upstream provider, you should consider their ability to   deal with the Internet infrastructure.   What will you be doing and what role will you play?   o  If you are interested in connecting yourself (or a small      organization), you are an Internet end user.  You will probably      want to contact an Internet Service Provider (ISP) for most of      your needs.  Read section I and the first part of section II.   o  If you are interested in connecting your organization and in      having address space to distribute within your network, you are an      Internet high volume end user.  You will need more address space,      but still may chose to work with an Internet Service Provider      (ISP) for most of your needs.  Read sections I and II.   o  If you are interested in connecting your organization, and in      distributing addresses to your clients (who are end users), you      are an Internet Service Provider (ISP).  You will need to contact      a Local Internet Registry (if one is available, or your upstream      provider).  Read section I and continue reading the rest of this      document.Wenzel, et al.               Informational                      [Page 3]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   o  If you are interested in distributing addresses to your clients      and your clients are in turn distributing addresses, you are a      Local Internet Registry or large ISP.  You will probably need to      contact the Regional Internet Registry in your geographical area.      Read section I and continue reading the rest of this document.I.      Preparation of Systems and Network Planning   STEP ONE: PREPARE INFORMATION, ORGANIZE HARDWARE, FIGURE OUT TO WHOM   YOU WILL CONNECT, AND TEST IN-COUNTRY SYSTEMS.A.  What do I need to connect to the Internet?   You can connect using dial-up or dedicated lines, and you can choose   UUCP or IP.  It is preferable to be running the UNIX operating system   with TCP/IP over a dedicated line, although you can begin by using   UUCP over a dial-up line.  Although there are alternatives to UNIX,   for historical reasons and robustness UNIX is better prepared to   handle Internet connectivity.  It is best to use TCP/IP inside your   network even if you use another method for your external   connectivity.   You will need to obtain an Internet Protocol (IP) address, or block   of addresses, and a domain name.  You may also need an Autonomous   System Number (ASN) and an IN-ADDR.ARPA (reverse addressing) domain   name.  However, you may begin by having dial-up connectivity to   another organization that supports one or more mail exchange (MX)   record(s) for your site.  This would allow you to receive email at   your own domain name without requiring you to invest as much   initially.B.  What connectivity medium should I choose?   You may be constrained by telecommunications regulations in your   country as to your choice of dial-up, digital phone lines, fiber   optic cable, or satellite suppliers.  If not, cost, bandwidth, and   reliability will determine your choice.C.  What else do I need to do?   Before you do anything else:   1. Designate an administrative contact person and a technical contact   person.   Choose one person to be the administrative contact and another person   to be the technical contact.  Write down their full names, email and   postal addresses, and telephone and fax numbers (with countryWenzel, et al.               Informational                      [Page 4]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   prefixes in the form + country code (e.g., +011), city code, and   local telephone number).  The administrative contact should be a   member of your organization and must reside in the country.  The   technical contact should be the key network support person and may be   represented initially by someone outside of the country.  Note that   the technical contact must transition to a network support person   residing in the country.  The Internet Registries will request this   information in the form of database entries called objects.  For   example, on the RIPE template, the administrative contact should be   listed in the admin-c field in the database objects, and the   technical contact in the tech-c field in the database objects (more   information on database objects follows in section II D below).   2. Determine your cost-recovery charging scheme, if needed, so that   you can sustain operations.   No form or record will specifically request this, but it is important   that you project your costs adequately so that you can assess fees to   cover them and ensure stability of operations.   3. Diagram your network topology.   Determine the number of groups and end users.  Describe the size and   shape of your current network.  Design your addressing plan based on   this information.  It may be helpful to consider your organization   chart when doing this, if you anticipate it to be fairly stable.   If you are restricted to using the local telecommunications company's   telephone circuit, choose your circuit carrier based on capacity and   where it lands geographically.  Consider an asymmetric circuit, e.g.,   128kbps in and 64kbps out, if you expect to have more incoming   traffic than outgoing (e.g., if most of the traffic is expected to   originate from web servers outside your network).   4.  Determine to whom you will connect.   See the prerequisites section for types of connection providers that   might be appropriate for your situation.  Determine which ISP or   telecommunications company best fits your connectivity needs.   5.  Predict your address space and bandwidth requirements from end   user needs.   Since address space is finite and must be conserved, end users are   not permitted to reserve address space.  Address space is based on   what your needs are and how you justify those needs.  Evaluation of   IP address space requests is usually based on the documentation you   provide for the following 24 months (as perRFC 2050), as specifiedWenzel, et al.               Informational                      [Page 5]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   in the address space usage template and in the addressing plan you   submit.  Once you have used your assigned address space, you can   request additional space based on an updated estimate of growth in   your network.  This usually includes detailed documentation, updating   the appropriate regional registry database with details of your end   user assignments, and assigning address space both conservatively and   efficiently.   You will need to justify your needs for address space by   communicating your network design and should be prepared to clearly   present your plan for effective use of the request.  Determine your   current and future user needs.  If you are offering virtual web   services, it is no longer necessary to assign one IP address per   domain.  HTTP/1.1 defines the "host" header to allow vanity names   without the use of an IP address.  Allocations for points of presence   (POP) throughout your region should also be determined.  Predictions   of user behavior can be based on analysis of published rates,   interviews with individual and institutional subscribers, and case   histories of other countries (see "History of the Internet in   Thailand").  For example,      Area1        10 dialup modems        10 leased lines to organization's LANs (size of the LANs)      Area2         5 dialup modems      Main POP         5 servers: mail, WWW, DNS, FTP, etc.   When you design your plan, you should design it for what you need   now, what you believe you will need six months from now, and then one   year and two years from now.   6.  Set up, connect, and test your hardware and software.   It is important to ensure that you have enough representative systems   set up and their connectivity tested using temporary addresses before   contacting the appropriate agency for address space.D.  How do I get the documents referred to in this guide?   SeeAppendix B for details on obtaining the documents referred to in   this guide.E.  Section References   For more information on TCP/IP, seeRFC 2151, "A Primer on Internet   and TCP/IP Tools and Utilities".Wenzel, et al.               Informational                      [Page 6]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000II.     Address Space Allocation   STEP TWO: OBTAIN ADDRESS SPACE ALLOCATION AND REGISTRATION FROM THE   ISP YOU ARE CONNECTING TO, OR (AS A LAST RESORT) YOUR REGIONAL   REGISTRY.   Internet Protocol (IP) addresses (under the current version 4) are   32-bit numbers usually expressed as 4 octets in dotted decimal   notation (for example, 128.223.162.27, which is the IP address for   the Network Startup Resource Center (NSRC) web server at the time of   this writing).  Public IP addresses make up the Internet address   space.  Addresses are allocated in a hierarchical manner and are   designed to be unique.   The Internet Assigned Numbers Authority (IANA) allocates large   address blocks to the three current Regional Internet Registries   (IRs): ARIN, APNIC, and RIPE NCC which, in turn, allocate smaller   blocks to Local Internet Registries or large ISPs.  Local Internet   Registries, which are typically ISPs or collections of ISPs   represented at a country level, and large ISPs process the vast   majority of address space assignments to ISPs and end users   Contact the Internet service provider from whom you are getting your   connectivity services (your upstream provider) with an address   allocation request.  It is important and required that you contact   your upstream provider first, and not the Regional IR automatically.   The first question the Regional Registry will ask you is why you   cannot get address space from your upstream provider.A.  Who is my upstream provider?   If there is an ISP already functioning in your country, contact them   directly.  If you are to be the first connection in your country, you   may need to contact your Regional IR in your geographic region, but   you should always contact your upstream provider first for assistance   and guidance.  Since address allocation is hierarchical, the   administrative organizations and procedures also represent this   hierarchical structure.  It is important not to skip a step in the   hierarchy.  Current Regional Registries include ARIN (the Americas,   Caribbean, and Africa), RIPE (Europe, Africa, and the Middle East),   and APNIC (the Pacific Rim and Asia).  Contact information for these   organizations is listed inAppendix A.   You should contact your Regional Internet Registry if 1) the ISP you   are connecting to is unable or unwilling to provide address space, or   2) your particular connectivity requirements will result in non-local   data to your customers possibly taking a different route over the   Internet than data destined for your upstream provider's customers,Wenzel, et al.               Informational                      [Page 7]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   or 3) you anticipate a quick growth rate that may require changing   your current upstream provider to a larger one and you wish to avoid   the renumbering that such a move would require.B.  How much address space should I ask for?   Regional IRs typically assign address blocks on the basis of an   immediate need and projected utilization rate within one year.  (If   you are in the ARIN region, it is one year for end user organizations   and three months for ISPs.)  Calculate your address space request   accordingly.  It is recommended to include the organization chart and   network topology diagram referred to in section I.C, number 3   (above).  Note that address space is allocated based on CIDR bit   boundaries (see next section).  The registries will need to   understand your network engineering and deployment plans in   significant detail before they can allocate address space.   Therefore, the more detailed information you can provide, the more   likely your request will be processed quickly.   If you obtain address space from your ISP, it is very likely that you   will need to renumber should you decide to change upstream providers   and/or if you grow considerably.  As this renumbering may affect your   customers (and their customers, etc.) if they are using dedicated   lines, you should carefully weigh the cost/benefit involved in   obtaining address space from your upstream provider.   If you are singly homed, you should obtain your address space from   your upstream ISP.  If you plan on enlarging but remaining singly   homed, you should continue to obtain space this way as it promotes   aggregation.  If, however, you plan to be multi-homed as part of your   growth plan, it would make sense to become a member of an appropriate   Regional IR (or, if one exists in your region, a national Network   Information Center (NIC) and obtain a /19 or "provider aggregatable"   address space.   The minimum routable block is often a /19, so if you plan on   enlarging, it is better to pay the fees to the Regional IR now and   obtain a /19 block so that you will not have to renumber later.  Note   that if you are an ISP in the ARIN region, ARIN  has special   requirements before you can do this in terms of the amount of address   space you have previously used, which must be a /21.  The current   policy is that you must have used a /19 previously from your upstream   ISP before going to ARIN, or you must be multi-homed and show you   have used a /21 and be willing to renumber and ARIN will issue a /20   from a reserved /19.Wenzel, et al.               Informational                      [Page 8]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   As of February 8, 1999, ARIN lowered the minimum allocation size for   IP addresses from a /19 to a /20.  ARIN will issue initial   allocations of prefixes no longer than /20.  If allocations smaller   than /20 are needed, ISPs and end users should request address space   from their upstream provider.  ARIN does not guarantee that addresses   will be globally routable.   APNIC and RIPE NCC do not have these requirements.  For APNIC, new   allocations to members will be a /19.   Remember that your upstream provider should route you if you ask   them.  You are a customer of the ISP, so if the service is not what   you need you should change ISPs.   IF YOU ARE CONNECTED TO ONLY ONE PROVIDER, AND ARE NOT VERY LARGE   YET, GET AN ADDRESS RANGE FROM YOUR PROVIDER.  SKIP THE REST OF THIS   SECTION AND ALL OF SECTION V.C.  What is CIDR?   CIDR stands for Classless Inter-Domain Routing.  Historically, IP   addresses were assigned within classes: Class A (8 bits of network   address, 24 bits of host address), Class B (16 bits of network   address, 16 bits of host address), or Class C (24 bits of network   address, 8 bits of host address).  With the advent of CIDR, address   space is now allocated and assigned on bit boundaries.  Using CIDR   means you are able to assign addresses corresponding with the number   of hosts on the network, thereby conserving address space.   The following table illustrates this:   Addrs Bits  Pref  Class         Mask   1       0       /32                     255.255.255.255   2       1       /31                     255.255.255.254   4       2       /30                     255.255.255.252   8       3       /29                     255.255.255.248   16      4       /28                     255.255.255.240   32      5       /27                     255.255.255.224   64      6       /26                     255.255.255.192   128     7       /25                     255.255.255.128   256     8       /24     1C              255.255.255.0   512     9       /23     2C              255.255.254.0   1K      10      /22     4C              255.255.252.0   2K      11      /21     8C              255.255.248.0   4K      12      /20     16C             255.255.240.0   8K      13      /19     32C             255.255.224.0Wenzel, et al.

You will need to send a database object to the appropriate registry   to request and register address space.  The registration databases   are composed of records that are a series of fields separated by one   or more blank lines; each field consists of two parts, the tag and   the value.  Do not modify the tags in the templates or errors will   occur.  Values for particular fields are specified in the templates;   be careful to enter appropriate information.   The first line of a template denotes the record type.  For example,   an IP address template's first line is inetnum, therefore the record   is known as an inetnum object.  This first line is also used as the   primary key for the record, therefore if you want to modify the first   field of the record, the only way to do so is to delete the record   entirely and add a new record with the corrected information.   For illustration, here is the RIPE inetnum object.      inetnum: [IP address range that will be assigned]      netname: Network-Name      descr: Network-Name Communications Company, Town      admin-c: NIC-handle of administrative contact      tech-c: NIC-handle of technical contact      country: ISO 3166-country-codeWenzel, et al.

Autonomous Systems (AS)   STEP THREE:  IF NEEDED, OBTAIN AN AUTONOMOUS SYSTEM NUMBER.A.  What is an ASN and do I need one?   Autonomous System Numbers (ASNs) are used to facilitate routing in   multi-homed environments.  They are allocated when your routing   policy is different from your provider's.  This generally means your   site is multi-homed.  In nearly all cases, unless you are multi-homed   to more than one ISP, you will not need an ASN.  If your routing   policy does not differ from your service provider's, you should useWenzel, et al.               Informational                     [Page 13]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   the service provider's ASN.  If there is constant traffic between you   and a point in another country, you may want to connect to a second   ISP in that country.  Note that the resultant multi-homing generally   makes the system more robust and may also change registry (and   therefore request) relationships.  It also increases costs greatly.   You may have to reduce traffic on your international lines by   choosing to connect to a local exchange point.  This allows traffic   to stay within your country and off of expensive international links.   If you implement this plan, you will be multi-homed and will need to   read the autonomous systems and routing sections of this document.B.  How do I register an ASN?   Since the ASN space is quite limited, request only what you really   need when you need it.   For Countries in the APNIC Region   APNIC-066 is the ASN Request Form. The form is located at:http://ftp.apnic.net/apnic/docs/asn-request   Send the completed form via email to APNIC at:      hostmaster@apnic.net   For Countries in the ARIN Region   A complete listing of assigned ASNs is located at:ftp://rs.arin.net/netinfo/asn.txt   The ASN registration form is located at:ftp://rs.arin.net/templates/asntemplate.txt   orhttp://www.arin.net/templates/asntemplate.txt   Send the completed form via email to ARIN at:      hostmaster@arin.net   with "ASN request" in the subject field.Wenzel, et al.

Section References   For more information on ASNs, seeRFC 1930, "Autonomous Systems   (AS)".IV.     Routing and Exchange Points   STEP FOUR: IF NEEDED, REGISTER WITH A ROUTING DATABASE.A.  Do I need to register with a routing database?   You do not need to register with a routing database if you are simply   carrying default routes to your (single) ISP.  If you get your   address space from an ISP, the ISP will register you.  If you are   connected to more than one ISP, then you should register with a   routing database.   The more multi-homed you are, the larger your routing tables need to   be.  If you are connected to public exchange points (see examples   below), or to more than one backbone ISP, you need to carry full   routing tables and run without a default route.   Example European Exchange Points:   LINX            London Internet Exchange   M9-IX           Moscow Internet Exchange   NIX.CZ          Neutral Internet Exchange, Czech Republic   Example Asia/Pacific Exchange Points:   AUIX            Australia Internet Exchange   HKIX            Hong Kong Internet Exchange   JPIX            Japan Internet ExchangeWenzel, et al.               Informational                     [Page 15]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   Example Americas Exchange Points:   MAE-EAST        Metropolitan Area Ethernet - East   MAE-WEST        Metropolitan Area Ethernet - West   PAIX            Palo Alto Internet Exchange   Depending on the requirements of your international ISP, you may be   able to have only a default route to them and specific routes to   other suppliers if you have an in-country exchange point.  Or they   may require that you carry a full set of routes, treating your   connection to the in-country exchange point as if it were a multi-   homed connection.B.  What about CIDR and routing?   All registries use CIDR. All major router vendors (Cisco, 3Com,   Nortel, Proteon, IBM, etc.) support CIDR.  CIDR Internet routers use   only the prefix of the destination address to route traffic to a   subnetted environment.C.  How do I choose a routing database?   The Internet Routing Registry (IRR) describes registries maintained   by several national and international networking organizations.   These currently include the RIPE Network Coordination Centre (NCC),   ANS (Advanced Network Solutions, Inc.), Bell Canada (formerly   CA*net), Cable and Wireless (CW), and the Routing Arbiter Database   (RADB).  The IRR is a way for ASNs to publicize their own intended   routing policies without having to request a change from a go-   between.   "whois" queries to "whois.ra.net" return data that they gather from   the entire IRR set of routing registries.  Tools such as "peval" and   "rtconfig" return data only from the RADB.  Thus, when running those   tools and desiring data from a set of registries, one must enumerate   them as in the following example.  "whois" queries to the client   configure the precedence of routing databases.  For example:      @RtConfig set sources = "TEST, RADB, RIPE, ANS, BELL, CW"   There are several other registries, such as ALTDB.  A list, and other   information on RADB, is available at:http://www.radb.net/   As of January 1, 2000, the transition to the Routing Policy   Specification Language (RSPL) is complete.  RIPE-181 object   submissions are no longer accepted.  For more information, see:Wenzel, et al.               Informational                     [Page 16]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000http://www.merit.edu/radb/announce.html   With the exception of the Routing Arbiter Database, each registry   serves a limited customer base.  ANS, Cable and Wireless, and Bell   Canada accept routing registrations for their customers alone, and   the RIPE NCC oversees European registrations. The Routing Arbiter   Database is unique in that it handles registrations for networking   organizations not covered by the other routing registries. The   Routing Arbiter also provides coordination among all the registries   to ensure consistent representation of routing policies.   All Regional IRs need to register with one (only one) of the routing   databases in the IRR. If you are announcing routes via BGP4, you need   to register your routes in the Routing Registry in only one of the   IRR's.  Logically, this will be the "closest" IRR to you.  However,   note that some ISPs do not use the regional registries or RADB.D.  How do I register in the RADB (The Americas)?   You need to submit three types of database records to the RADB: one   or more maintainer objects, an AS object, and one or more route   objects.   To specify the individuals who are allowed to update your records in   the RADB, fill out one or more maintainer objects and send them via   email to:      db-admin@radb.net   You need to submit a maintainer object before you can register any AS   or route objects.   To describe the autonomous system that announces your routes, fill   out an AS object and submit it via email to:      auto-dbm@radb.net   AS objects are also called aut-num objects.   To register your routes, fill out one or more route objects, and send   them to RADB via email to:      auto-dbm@radb.net   Note that most of the IRR participants have the auto-dbm@xx.net email   address function for accepting updates to the IRR automatically.Wenzel, et al.

Domain Name Registration   STEP FIVE:  REGISTER YOUR DOMAIN NAME.A.  What is a country domain?   The Domain Name System (DNS) specifies the naming of computers within   a hierarchy.  Top-Level Domain (TLD) names include generic TLDs   (gTLDs) and two-letter country codes (ccTLDs).  Examples of gTLDs   include .com (commercial), .net (network), and .org (organization).   Examples of two-letter country codes are .ca for Canada, .fr for   France, and .id for Indonesia.  ISO 3166 is used as a basis for   country code top-level domain names.  Country codes are assigned by   the International Organization for Standardization (ISO) in   cooperation with the United Nations.  The Internet Assigned Numbers   Authority (IANA) directly registers all country-code top-level   domains, however it is not involved in the allocation of codes to   countries.  IANA is a function of the Internet Corporation for   Assigned Names and Numbers (ICANN, seeAppendix A).  See ISO 3166 for   more information and a current listing of country codes (Appendix C).   A hierarchy of names may, and normally should be, created under each   TLD.  There is a wide variation in the structure of country domains.   In some countries there is a substantial hierarchy, while in others   the structure is flat.  In some country domains the second levels are   generic categories, while in others they are based on geography, and   in still others, organization names are listed directly under the   country code.  Examples of second level generic categories are ac or   edu (academic or education), co or com (corporate or commercial), and   go or gov (government).B.  How do I register as a country domain?   First check that: (1) the domain is still available, few are, (2) you   have someone in your country as the administrative contact, and (3)   your name servers are prepared (seeRFC 1912 for information on   common errors in preparing name servers).Wenzel, et al.               Informational                     [Page 18]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   The whois master database is the authoritative source of information   on .com, .net, .org, and .edu domain name registrations.  It is   currently maintained by Network Solutions, Inc. and holds referral   pointers to which whois database contains the record for the domain   name.   To apply to manage a country code top-level domain you should:   1. First, if you are on a UNIX host, use the "whois" command to see   if the domain is already registered:      whois =<domain>   2. If the domain does not already have an administrative contact,   request a Domain Name Agreement template from IANA by sending email   to:      iana@iana.orgC.  What if my country is already registered?   If your country is already registered, contact the country-code   administrator to register a new second-level domain name.   Please note that ARIN, RIPE, and APNIC do not handle domain names   (other than IN-ADDR.ARPA).  If you want to register a domain name   directly under a top-level domain (TLD), please contact the   appropriate TLD administrator.D.  How do I resolve a country domain name dispute?   SeeRFC 1591 for domain name dispute information.  Note that you will   need to resolve the dispute within your country before you contact   IANA.E.  Section References   For more information on domain names, seeRFC 1591, "Domain Name   System Structure and Delegation";RFC 1713, "Tools for DNS   Debugging"; andRFC 1912, "Common DNS Operational and Configuration   Errors".VI.     IN-ADDR.ARPA Domain Delegation   STEP SIX:  IF NEEDED, REGISTER YOUR IN-ADDR.ARPA DOMAIN.Wenzel, et al.               Informational                     [Page 19]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000A.  What is an IN-ADDR.ARPA domain and do I need one?   An IN-ADDR.ARPA domain allows for mapping of IP addresses into domain   names.  This is often referred to as "inverse addressing" because it   is the opposite of the domain name to IP address resolution.  IN-ADDR   domains are represented using the network number in reverse.  For   example, the IN-ADDR domain for network 123.45.67.0 is represented as   67.45.123.in-addr.arpa.   You almost always need reverse resolution.B.  How do I register an IN-ADDR.ARPA domain?   You should ask your upstream provider about registering your IN-   ADDR.ARPA domains.  If you are working directly with a regional   registry, see below.   For Countries in the APNIC Region   The IN-ADDR.ARPA Delegation Form is APNIC-064 and is located at:ftp://ftp.apnic.net/apnic/docs/in-addr-request   CAUTION: You must set-up your name server to accept the delegation   prior to submission of this form.   Send the completed form via email to APNIC at:      domreg@rs.apnic.net   For Countries in the ARIN Region   How IN-ADDR.ARPA is registered is dependent on the registration of   the block needing reverse entries.  For example, all blocks that have   been registered directly from the Regional IR may have IN-ADDR.ARPA   delegation established by ARIN.  In this case, IN-ADDR.ARPA   delegations are registered using the ARIN modify template.  This   template can be found at:ftp://ftp.arin.net/templates/modifytemplate.txt   orhttp://www.arin.net/templates/modifytemplate.txt   Instructions for completing the template can be found at the bottom   of the template.   CAUTION: Do not list your network number in reverse on the template.Wenzel, et al.               Informational                     [Page 20]

RFC 2901      Administrative Internet Infrastructure Guide   August 2000   Send the completed form via email to ARIN at:      hostmaster@arin.net   All blocks that have been reassigned to your organization by an ISP   will have IN-ADDR.ARPA established by your provider.  In this case,   contact the ISP that reassigned IP address space to your organization   and coordinate IN-ADDR.ARPA delegation.   For Countries in the RIPE Region   The domain object needs to be entered in the RIPE database before   requesting reverse delegation.   domain: 0.194.in-addr.arpa   descr: Our organization allocation   admin-c: NIC-handle of administrative contact (e.g., JLC-2RIPE)   tech-c: NIC-handle of technical contact   zone-c: NIC-handle of zone contact   nserver: Name server (e.g., ns.someserver.net)   nserver: ns.otherserver.net   nserver: ns.ripe.net   changed: email@address.net 960731   source: RIPE   NOTE:  One of the name servers has to be ns.ripe.net   The domain object described above should be included in the request,   as well as zone file entries for the zone above the one requested.   For example, if a reverse delegation is requested for 1.193.in-   addr.arpa, the relevant zone file entries should be included for   193.in-addr.arpa; whereas if a reverse delegation is requested for   2.2.193.in-addr.arpa, the zone file entries should be included for   2.193.in-addr.arpa.   Send the completed object(s) via email to RIPE at:      auto-inaddr@ripe.netVII.    SecurityA.  Is there a way to prevent unauthorized changes to my objects?   Registries provide various security measures to prevent unauthorized   changes to your database entries.  Contact your regional IR for more   information.  Note that the contact information you provide in the   database object registrations is not private.Wenzel, et al.               Informational                     [Page 21]
