RFC 4698               IRIS Address Registry Type           October 20061.  Introduction   An Internet address registry stores information about:   o  address ranges   o  autonomous system number ranges   o  associated contacts and organizations   o  name servers   This information is interrelated, and Internet address registries   store this information and the information's interrelationships in a   manner befitting the needs of each Internet address registry and its   constituents.  This document specifies a method for accessing and   retrieving this information in a common XML format.   This document describes an IRIS namespace for Internet address   registries using an XML Schema [8] derived from and using the IRIS   [2] schema.  This schema and registry type are provided to   demonstrate the extensibility of the IRIS framework beyond the use of   domains, a criteria defined in CRISP [4].   The schema given is this document is specified using the Extensible   Markup Language (XML) 1.0 as described in XML [5], XML Schema   notation as described in XML_SD [7] and XML_SS [8], and XML   Namespaces as described in XML_NS [6].   Examples of client/server XML exchanges with this registry type are   available inAppendix B.2.  Document Terminology   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this   document are to be interpreted as described inRFC 2119 [1].3.  Schema Description   IRIS requires the derivation of both query and result elements by a   registry schema.  Descriptions for these follow.   The descriptions contained within this section refer to XML elements   and attributes and their relation to the exchange of data within the   protocol.  These descriptions also contain specifications outside the   scope of the formal XML syntax.  Therefore, this section will use   terms defined byRFC 2119 [1] to describe the specification outsideGunduz, et al.              Standards Track                     [Page 3]

While reading this section,   please referenceSection 5 for needed details on the formal XML   syntax.3.1.  Query Derivatives3.1.1.  <findContacts> Query   <findContacts> searches for contacts given search constraints.   The allowable search fields are handled by one of the elements in the   "contactSearchGroup" (seeSection 3.1.9) or the element   <organizationId>.  The <organizationId> element constrains the query   based on the organization ID (handle) associated with contacts.  This   element is an "exactMatchParameter" (seeSection 3.1.11).   This query also provides optional <language> elements containing   language tags.  Clients MAY use these elements to give a hint about   the natural language(s) of the affected element.  Servers MAY use   this information in processing the query, such as tailoring   normalization routines to aid in more effective searches.   The client SHOULD pass the names unchanged to the server, and the   implementation of the server decides if the search is case sensitive   or not.3.1.2.  <findOrganizations>   <findOrganizations> searches for organizations given search   constraints.   The allowable search fields are handled by one of the elements in the   "commonSearchGroup" (seeSection 3.1.10) or the element   <organizationName>.  This element is an   "exactOrPartialMatchParameter" (seeSection 3.1.11).   This query also provides optional <language> elements containing   language tags.  Clients MAY use these elements to give a hint about   the natural language(s) of the affected element.  Servers MAY use   this information in processing the query, such as tailoring   normalization routines to aid in more effective searches.   The client SHOULD pass the names unchanged to the server, and the   implementation of the server decides if the search is case sensitive   or not.Gunduz, et al.              Standards Track                     [Page 4]

RFC 4698               IRIS Address Registry Type           October 20063.1.3.  <findAutonomousSystemsByName> and <findNetworksByName>   The <findAutonomousSystemsByName> and <findNetworksByName> elements   allow searches by name of autonomous systems and networks,   respectively.  Both have the same format.   The child element <name> is an "exactOrPartialMatchParameter" (seeSection 3.1.11).   This query also provides optional <language> elements containing   language tags.  Clients MAY use these elements to give a hint about   the natural language(s) of the affected element.  Servers MAY use   this information in processing the query, such as tailoring   normalization routines to aid in more effective searches.   The client SHOULD pass the names unchanged to the server, and the   implementation of the server decides if the search is case sensitive   or not.3.1.4.  <findNetworksByAddress>   The <findNetworksByAddress> element is a query for a network given a   related IP address or IP address range.  It has the following child   elements:   o  <ipv4Address> - has a child <start> element containing the      starting IPv4 address of the network and an optional child of      <end> containing the ending IPv4 address of the network.  Clients      MUST convert any short-form notation to the fully-qualified      notation.   o  <ipv6Address> - same as <ipv4Address>, but the child addresses      contain IPv6 addresses.  Clients MUST convert any short-form      notation to the fully-qualified notation.   o  <specificity> - determines the network specificity for the search      (seeSection 4).  Valid values are "exact-match", "all-less-      specific", "one-level-less-specific", "all-more-specific", and      "one-level-more-specific".  This element may have the optional      attribute 'allowEquivalences'.  When it is set to "true", the      result set should include networks with equivalent starting and      ending addresses.  The default value for 'allowEquivalences' is      "false".   The results from this query MUST be either <ipv4Network> or   <ipv6Network> results.  More than one network result MAY be returned.Gunduz, et al.              Standards Track                     [Page 5]

RFC 4698               IRIS Address Registry Type           October 20063.1.5.  <findNetworksByHandle>   The <findNetworksByHandle> element is a query for a network given a   the handle of a related network.  It has the following child   elements:   o  <networkHandle> - specifies the network handle.   o  <specificity> - determines the network specificity for the search      (seeSection 4).  Valid values are "all-less-specifics", "one-      level-less-specifics", "all-more-specifics", and "one-level-more-      specifics".   The results from this query MUST be either <ipv4Network> or   <ipv6Network> results.  More than one network result MAY be returned.   This query could be used to discover the parentage relationships   between networks that have the same starting and ending addresses.   The client SHOULD pass handles unchanged to the server, and the   implementation of the server decides if the search is case sensitive   or not.3.1.6.  <findASByNumber>   The <findASByNumber> element allows a search for autonomous systems   given an autonomous system number (ASN) range.  It has the following   child elements:   o  <asNumberStart> - specifies the start of the ASN range.   o  <asNumberEnd> - specifies the end of the ASN range.   o  <specificity> - determines the range specificity for the search      (seeSection 4).  Valid values are "exact-match", "all-less-      specific", "one-level-less-specific", "all-more-specific", and      "one-level-more-specific".  This element may have the optional      attribute 'allowEquivalences'.  When it is set to "true", the      result set should include ranges with equivalent starting and      ending numbers.  The default value for 'allowEquivalences' is      "false".   The results from this query MUST be <autonomousSystem> results.  More   than one result MAY be returned.Gunduz, et al.              Standards Track                     [Page 6]

RFC 4698               IRIS Address Registry Type           October 20063.1.7.  <findByContact>   The <findByContact> element allows a search for autonomous systems,   IP networks, and organizations on fields associated with that   entity's contact.  The optional search element <returnedResultType>   MUST restrict the results to autonomous systems, IPv4 networks, IPv6   networks, or organizations using the values 'returnASs',   'returnIPv4Networks', 'returnIPv6Networks', and   'returnOrganizations', respectively.   The allowable search fields are handled with either the   <contactHandle> element or one of the elements in the   "contactSearchGroup" (seeSection 3.1.9).  The <contactHandle>   element allows for the entities to be selected based on the contact   having the specified contact handle, and it is an   "exactMatchParameter" type (seeSection 3.1.11).  The client SHOULD   pass these search fields unchanged to the server, and the   implementation of the server decides if the search is case sensitive   or not.   The query MAY also be constrained further using the optional <role>   element.  The contents of this element signify the role the contact   has with the entity.  The allowable values for this element are   "adminContact", "nocContact", "techContact", "abuseContact", and   "otherContact".   This query also provides optional <language> elements containing   language tags.  Clients MAY use these elements to give a hint about   the natural language(s) of the affected element.  Servers MAY use   this information in processing the query, such as tailoring   normalization routines to aid in more effective searches.   The results from this query MUST be <ipv4Network> results,   <ipv6Network> results, <autonomousSystem> results, or <organization>   results.  More than one result MAY be returned, and the results MAY   be of mixed types.3.1.8.  <findNetworksByNameServer>   The <findNetworksByNameServer> element allows a search for IP   networks based on their associated name servers.  The <nameServer>   element contains the fully qualified domain name of the name server.   The optional search element <returnedResultType> MUST restrict the   results to IPv4 networks or IPv6 networks using the values   'returnIPv4Networks' and 'returnIPv6Networks', respectively.Gunduz, et al.              Standards Track                     [Page 7]

RFC 4698               IRIS Address Registry Type           October 2006   The results from this query MUST be <ipv4Network> or <ipv6Network>   results.  More than one result MAY be returned, and the results MAY   be of mixed types.3.1.9.  Contact Search Group   Some of the queries above have similar query constraints for   searching on contacts.  This section describes those common   parameters.   <commonName> allows the query to be constrained based on the common   name of the contact.  This constraint is an   "exactOrPartialMatchParameter" (seeSection 3.1.11).   This group also contains all the members of the "commonSearchGroup"   (seeSection 3.1.10).3.1.10.  Common Search Group   Some of the queries above have similar query constraints for   searching on contacts.  This section describes those common   parameters.   <eMail> constrains the query based on the e-mail address of the   contact.  This constraint is a "domainResource" type (seeSection 3.1.11).   The <city>, <region>, <country>, and <postalCode> elements restrict   the scope of the query based on the city, region, country, or postal   code of the contact, respectively.  These constraints are all   "exactMatchParameter" types (seeSection 3.1.11).  The contents of   <country> MUST be compliant with ISO 3166 [9] two-character country   codes.3.1.11.  Match Parameters   Some of the queries above have constraints that match strings using   matching parameters.  This section describes those matching   parameters.   Elements of type "exactMatchParameter" will have one child element of   <exactMatch>.  The contents of this child element are to match   exactly in the use of the constraint.   Elements of type "partialMatchParameter" will have either a   <beginsWith> child element with an optional <endsWith> child element   or an <endsWith> child element.  The content of the <beginsWith>Gunduz, et al.              Standards Track                     [Page 8]

RFC 4698               IRIS Address Registry Type           October 2006   element specifies the beginning character sequence for the   constraint.  The content of the <endsWith> element specifies the   ending character sequence for the constraint.   Elements of type "exactOrPartialMatchParameter" can have either the   child element allowed with the "exactMatchParameter" type or the   child elements allowed with the "partialMatchParameter" type.   Elements of type "domainResource" can have either the child element   allowed with the "exactMatchParameter" type or a child element of   <inDomain>.  This parameter type is meant to match email, SIP,   Extensible Messaging and Presence Protocol (XMPP), and other types of   "user@domain" addresses.  When this parameter is specified with the   <exactMatch> child element, the constraint is based on the whole   email address.  When this parameter is specified with the <inDomain>   child element, the constraint is based on any email address within   the domain given.  The <inDomain> MUST only contain a valid domain   name (i.e., no '@' symbol), and the matching SHOULD take place only   on the domain given (i.e., no partial matches with respect to   substrings or parent domains).3.2.  Result Derivatives3.2.1.  <ipv4Network> and <ipv6Network> Results   The <ipv4Network> and <ipv6Network> share a common definition of   'ipNetworkType'.  It has the following child elements:   o  <networkHandle> contains the registry-unique assigned handle for      this network.   o  <name> contains a human-friendly name for the network.   o  <startAddress> contains the first IP address of the network.   o  <endAddress> contains the last IP address of the network.   o  <networkType> contains a string denoting the type of network.   o  <networkTypeInfo> is an entity reference to a definition of the      values explained in a plain natural language.

RFC 4698               IRIS Address Registry Type           October 20064.  Terminology for Nesting of Networks   The following terms are defined for describing the nesting of IP   networks.   o  More specific: Given two networks, A and B, A is more specific      than B if network B includes all space of network A, and if      network B is larger than network A.   o  Less specific: Opposite of more specific.  The network B is less      specific than network A if network A's space is completely      included in network B and if network A is smaller than network B.   o  Most specific: Given a set of networks, the network or networks      that are more specific than zero or more specific of the other      networks in the set, and that are not less specific of any of the      networks in the set.   o  Least specific: Given a set of networks, the network or networks      that are not more specific to any of the other networks in the      set.

A network overlaps with another one when   they encompass each other's space partially.  Examples:     A   |---------------------|     B       |----------------------------|                        Figure 3: Nesting Example 3   Here, networks A and B are overlapping networks because network A   encompasses network B's space partially, and network B encompasses   network A's space partially.     C   |------------------|     D   |---------|                        Figure 4: Nesting Example 4   Here, networks C and D are NOT overlapping networks because even if   network D encompasses a part of network C's space, network C does not   encompass network D's space partially (it encompasses network D   completely).   The address directory can contain more than one network with the same   range.  They are said to be exact match networks.   The parent/child relationship in the internet address directory is   unidirectional.  That is, there might also be parent/child   relationship with exact match networks, but a network cannot be a   parent and a child of its exact match network at the same time.Gunduz, et al.

RFC 4698               IRIS Address Registry Type           October 2006   The following are nested matching searches:   (1) all less specifics search: Given a range, find all the networks       that contain that range (i.e., all less specifics and exact       matches).  These networks are the networks that fulfill the       following condition:   (start(network) <= start(search)) AND (end(network) >= end(search))   (2) one-level less specifics search: Given a range, find only the       most specific network that contains that range (could be multiple       networks, but usually single).  This is the set of networks from       (1), with the provision that no network in the return set is       contained by any other network in the set.  If there are exact       match networks in the set from (1), they both must appear in the       result set.  The result set may contain a network that is exact       match to the query range, if the search allows exact matches.       A  |-------------------------------|       B  |---------------------------|       C            |-------|       Query  |- - - - - - - - - -|                          Figure 5: Nesting Example 5       In the above case, the query must return B.       A  |-------------------------------|       B  |---------------------------|       C  |---------------------------|       D            |-------|       Query  |- - - - - - - - - -|                          Figure 6: Nesting Example 6       Here, the query must return B and C (they are exact matches of       each other).       A  |-------------------------------|       B  |---------------------------|       C  |---------------------------|       D            |-------|       Query        |- - - -|                          Figure 7: Nesting Example 7Gunduz, et al.

RFC 4698               IRIS Address Registry Type           October 2006       Here, the query must return B and C (they are exact matches of       each other).  D must not be in the result set, as it is exact       match to the query if the search specifies that exact matches of       query range should not appear in the result set.       In Figure 7, if the search specifies that exact matches to the       query range are allowed in the result set, then only D must be       returned.   (3) all more specifics search: Given a range, find all the networks       that are fully within that range.  The search contains a flag       that specifies if an exact match to the query range should appear       in the result set or not.  Thus, the result set may or may not       contain the exact match to the query range, as instructed by the       search.   (start(network) >= start(search)) AND (end(network) <= end(search))   (4) one-level more specifics search: Given a range, find only the       least specific networks that are fully within that range.  This       is the set of networks from (3), with the provision that no       network in the return set contains any other network in the       return set.

That is, the       networks that fulfill the following condition:   (start(network) = start(search)) AND (end(network) = end(search))   (6) Given a range, find the exact match network if it exists, and if       it does not, perform the (2) search.   The following are parent-child relationship searches:   (7) Given a network handle, find the network that is the direct (one       level up) parent of the network with the given handle.Gunduz, et al.

RFC 4698               IRIS Address Registry Type           October 2006   (8) Given a network handle, find the network or networks that are       direct (one level down) children of the network with the handle       given.5.

RFC 4698               IRIS Address Registry Type           October 20066.  BEEP Transport Compliance   IRIS allows several extensions of the core capabilities.  This   section outlines those extensions allowable by IRIS-BEEP [3].6.1.  Message Pattern   This registry type uses the default message pattern as described in   IRIS-BEEP [3].6.2.  Server Authentication   This registry type uses the default server authentication method as   described in IRIS-BEEP [3].7.  URI Resolution7.1.  Application Service Label   SeeSection 9 for the application service label registration.7.2.  Operational Considerations   Address registries do not have natural links to DNS.  Using reverse   DNS tree presents problems for IP address delegation (for example,   delegations do not fall into byte boundaries, unlike reverse DNS),   and DNS does not currently contain any information regarding   autonomous system delegation.   Therefore, in order for the top-down resolution to operate properly,   it is requested that the IAB instruct IANA to insert and maintain a   NAPTR DNS resource record for areg.iris.arpa, as described inSection 9.7.3.  Top-Down Resolution   The top-down alternative resolution method MUST be identified as   'top' in IRIS URIs.   The process for this condition is as follows:   1.  The IRIS [2] direct-resolution process is tried against       areg.iris.arpa.   2.  If the direct-resolution process yields no server for which a       connection can be made, then a negative response is returned, and       no further action is taken.Gunduz, et al.              Standards Track                    [Page 31]

RFC 4698               IRIS Address Registry Type           October 2006   It is RECOMMENDED that IRIS clients issuing AREG1 requests use the   'top' resolution method when no resolution method has been explicitly   given by a user.  IRIS servers accepting AREG1 requests that seek   information for which they are not authoritative SHOULD refer clients   using the 'top' resolution method.8.  Internationalization Considerations   This document lays out no new considerations for internationalization   beyond those specified in IRIS [2].9.  IANA Considerations   The following URN has been registered with IANA according to the IANA   considerations defined in IRIS [2]:      urn:ietf:params:xml:ns:areg1   The following S-NAPTR application service label has been registered   with IANA according to the IANA considerations defined in IRIS [2]:      AREG1   Under instructions from the IAB, the IANA will create a new second   level domain under .arpa called iris (i.e., iris.arpa.).  The   contents of this new domain are to be under the control of the IAB.   Under instructions from the IAB, the IANA will insert and maintain a   NAPTR DNS resource record in the iris.arpa. domain for the name   areg.iris.arpa.  The initial contents for that record is:   areg.iris.arpa.   ;;        order pref flags service                   re replacement   IN NAPTR  100   10   ""    "AREG1:iris.xpc:iris.lwz" "" areg.nro.net10.  Security Considerations   This document lays out no new considerations for security precautions   beyond those specified in IRIS [2].Gunduz, et al.

RFC 4698               IRIS Address Registry Type           October 2006Appendix A.  Privacy Considerations   Internet address registries store contact details and other   information that may be abused.  The XML Schema defined in this   document purposefully makes the inclusion of any data in a response   an option that is dependent on the needs and policies of the Internet   address registry serving the data.   Combined with the authentication mechanisms of an IRIS transfer   protocol, Internet address registries may derive authorization   policies to meet their needs without compromising general privacy   policies.  As an example, the constituents of an Internet address   registry may create a policy whereby NOC contact email addresses are   only to be available to members of the Internet address registry.  To   institute this policy, the XML elements for NOC contacts will never   appear in a response to a user that has not been authenticated to be   a member of the Internet address registry.Appendix B.  Example Requests and Responses   The examples in this section use the string "C:" to denote data sent   by a client to a server and the string "S:" to denote data sent by a   server to a client.B.1.  Example 1   The following is an example of entity lookup for the contact-handle   of 'JN560-RIR1'.
