Network Working Group                         Federal Networking CouncilRequest For Comments: 1816                                   August 1995Obsoletes:1811Category: InformationalU.S. Government Internet Domain NamesStatus of this Memo   This memo provides information for the Internet community.  This memo   does not specify an Internet standard of any kind.  Distribution of   this memo is unlimited.Abstract   This memo provides an update and clarification toRFC 1811.  This   document describes the registration policies for the top-level domain   ".GOV".  Thus far, Federal Agencies and their subsidiaries have   registered without any guidance.  This has resulted in multiple   registrations for Federal Agencies and naming schemes that do not   facilitate responsiveness to the public.  This document fixes this by   restricting registrations to coincide with the approved structure of   the US government.  The document cited, FIPS 95-1, provides a   standard recognized structure into which domain registrations for   .GOV can be fit.  This policy is exactly comparable to that for the   top-level domains.  The IANA requires that an organization/country   apply for and get a 2 letter code from ISO/ITU (e.g., US for United   States) for additional top-level registration.   As a side effect, this reduces the number of .GOV level registrations   and reduces the workload on the Internic.U.S. GOVERNMENT INTERNET DOMAIN NAMES POLICY   The .GOV domain is delegated from the root authority to the US   Federal Networking Council.  The .GOV domain is for registration of   US governmental entities on the federal level only.  Registrations   for state and local governmental agencies shall be made under the .US   domain in accordance with the policies for that domain.   1) The document "Codes for the Identification of Federal and   Federally Assisted Organizations", FIPS 95-1 (or its successor)   lists the official names of US Government agencies.     A) Top-level entities (e.g., those with codes ending in 00 such as     "1200 Department of Agriculture"), and independent agencies and     organizations (e.g., "National Science Foundation and other non-Federal Networking Council   Informational                      [Page 1]

RFC 1816         U.S. Government Internet Domain Names       August 1995     indented listings unless prohibited below) as listed in this     document are eligible for registration directly under .GOV.     B) Autonomous law enforcement components of top-level entities     (e.g., "Federal Bureau of Investigation", "Secret Service", "Coast     Guard") are also eligible for registration.     C) Cross-agency collaborative organizations (e.g., "Federal     Networking Council", "Information Infrastructure Task Force") are     eligible for registration under .GOV upon presentation of the     chartering document and are the only non-FIPS-listed     organizations eligible for registration under .GOV.     D) Subsidiary, non-autonomous components of top-level or other     entities are not eligible for separate registration.     International organizations listed in this document are NOT     eligible for registration under .GOV.     E) Organizations listed as "Federally Aided Organizations" are not     eligible for registration under .GOV and should register under     .ORG or other appropriate top-level domain.     F) Organizations subsidiary to "Department of Defense" must     register under the ".MIL" domain via the Defense Data Network     Network Information Center - contact registrar@nic.ddn.mil.   The only standard exceptions to these rules are changes to   governmental structure due to statutory, regulatory or executive   directives not yet reflected in the above document.  The requesting   agency should provide documentation in one of the above forms to   request an exception.  Other requests for exception should be   referred to the Federal Networking Council.   2) A domain name should be derived from the official name for the   organization (e.g., "USDA.Gov" or "Agriculture.GOV".)  The   registration shall be listed in the registration database under the   official name (per FIPS 95-1) for the organization or under the name   in the chartering document.   3) Only ONE registration and delegation shall be made per agency.   The .GOV registration authority shall provide registrations on a   first-come first-served basis.  It is an individual agency matter as   to which portion of the agency is responsible for managing the domain   space under a delegated agency domain.   4) Those agencies and entities that have multiple registrations under   .GOV may retain them for a maximum of 3 years from the publicationFederal Networking Council   Informational                      [Page 2]

RFC 1816         U.S. Government Internet Domain Names       August 1995   date of this document.  Within 6 months after the publication of this   document, one permanent domain must be selected for the agency.  The   other (auxiliary) domains must cease further sub-delegations and   registrations at this time.  As of 1 year after the publication of   this document, the auxiliary domains will become undelegated and will   revert to the control of the .GOV owner. As of 2 years after the   publication of this document, all registrations in the auxiliary   domains must be mirrored in the permanent domain and those names should   be used where possible. At the 3 year point, all auxiliary domain   registrations will be deleted.   5) Those agencies and entities already registered in .GOV but not   listed in FIPS 95-1 (e.g., DOE labs, state entities) may retain their   registration within the constraint of the single registration rule   (see para 4).  No further non-FIPS-listed registrations will be made.   State and local entities are strongly encouraged to re-register under   .US, but this is not mandatory.References   [1] Federal Information Processing Standards Publication 95-1 (FIPS       PUB 95-1, "Codes for the Identification of Federal and Federally       Assisted Organizations", U.S. Department of Commerce, National       Institute of Standards and Technology, January 4, 1993.   [2] Postel, J., "Domain Name System Structure and Delegation",RFC1591, USC/Information Sciences Institute, March 1994.AddendumCLARIFICATION   * All current registrations in .GOV are grandfathered and do NOT   require re-registration with the exception of duplicate registrations   for the SAME organization at the same level.  E.g., two registrations   which represent the Department of Transportation would be duplicates;   registrations for each of the Department of Transportation and the   FAA would not (The FAA is an autonomous component contained within   the DOT).   * The policy requires resolution of all duplicate registrations   within the next three years.   * Local and state agencies registered under the ".GOV" domain may   remain there.  However, they are strongly encouraged to transfer to   the US domain.   * Cross-agency collaborative efforts may register under ".ORG" orFederal Networking Council   Informational                      [Page 3]

RFC 1816         U.S. Government Internet Domain Names       August 1995   ".US" as an alternative to asking for an exception to the policy.FREQUENTLY ASKED QUESTIONS / ANSWERSEXISTING .GOV REGISTRATIONS   Q.  What are examples of FIPS-95-1 Departments possessing duplicate   top level domain names, and what guidance has been given to them   regarding these names?   A.  Examples of FIPS-95-1 Departments with duplicate DNS' include   "STATE.GOV" and "LABOR.GOV".  These departments have six months to   determine which name is permanent and which is auxiliary and three   years to drop the auxiliary registration.   Q.  Currently, our services are defined as www.cdc.gov, ftp.cdc.gov,   and gopher.cdc.gov.  Does this proposal mean that our names will now   be: www.ntb.ops.cdc.phs.dhhs.gov, etc or at a minimum:   www.cdc.phs.dhhs.gov, ftp.cdc.phs.dhhs.gov, and   gopher.cdc.phs.dhhs.gov?   A.  In the case of CDC, NIST, NIH, FDA, and the numerous other non-   FIPS-95-1 agencies registered with ".GOV" domains, there will be no   changes.  The existing DNSs of these agencies are grandfathered under   this policy.  In addition, the policy effects only the domains   allowed to be registered directly under .GOV; further delegations are   under the control of the subdomain owner.  For the above, assuming   the HHS subdomain owner concurs, there is no problem with the HHS   registering "cdc.dhhs.gov" as a subdomain of "dhhs.gov".   Q.  How will registrations by Federal Laboratories be addressed?   A.  The existing domain names will be grandfathered, i.e., LBL.GOV.   Any new registrations will generally be within the domain of the   sponsoring agency (and subject to that agencies policies), within the   .US domain as a geographic entity, or within the .ORG domain.   Q.  What are some examples of state government agencies registered   under ".GOV" domain?  Will they need to change their DNS?   A.  Examples of cities and states that originally registered under   the ".GOV" include:        WA.GOV Department of Information Services, State of Washington        LA.GOV Bureau of Sanitation, City of Los AngelesFederal Networking Council   Informational                      [Page 4]

RFC 1816         U.S. Government Internet Domain Names       August 1995   These entities are strongly encouraged to reregister in the ".US"   domain but this is NOT mandatory.  No further state and local   agencies will be registered under .GOV.   Q.  It is not in anyone's best interest to name things by   organizational boundaries as these things change. Internet domain   names and host names, once defined and used, become so widely   distributed that they become virtually impossible to change.   Organizational structure changes but not the underlying networking   structure.   A.  The policy does not require organizations to change their names   once established, but individual agency policies may.  The DNS system   contains some capabilities to assist in name transition - the CNAME   record provides a capability for cross-domain aliases which can be   used to ease a transition between one name space and another.  As   noted in the clarifications, naming and subdomain conventions WITHIN   an agency or department DNS delegation are solely the province of   that entity.   Q.  How can two entities have the same name registered?  How does   this apply to NIH.GOV, FDA.GOV, and CDC.GOV, all of which are large   components of DHHS/PHS?  NCIFCRF.GOV is a component of NIH.  Does it   have to change?  I don't understand how a distinction is made if some   are grandfathered and some are not.   A. US-STATE.GOV and STATE.GOV for example.  The problem is actually   one entity with two names.  NIH.GOV and FDA.GOV represent separate   entities (albeit within DHHS).  If there were an NIH.GOV and an NIH-   EAST.GOV for example, NIH would have to eliminate one of them   (probably moving NIH-EAST.GOV to EAST.NIH.GOV).   Q.  How much is the taxpayer being asked to spend to alter tens of   thousands of existing computer and telecommunications systems to   supportRFC 1816?   A.  There are currently less that half-a-dozen duplicate DNS names at   the FIPS-95-1 level which will need to be changed.  Given the fact   that this will be accomplished over the next three years, the costs   should be minimal.Federal Networking Council   Informational                      [Page 5]

RFC 1816         U.S. Government Internet Domain Names       August 1995CROSS-AGENCY COLLABORATIONS   Q.  An organization maintains a domain name which represents a   cross-agency community, IC.GOV, which represents members of the   intelligence community.  As a cross-agency collaborative effort, does   the domain have to be reregistered?   A.  The policy states that "Cross-agency collaborative organizations   (e.g., "Federal Networking Council", "Information Infrastructure Task   Force") are eligible for registration under .GOV upon presentation of   the chartering document and are the only non-FIPS-listed   organizations eligible for registration under .GOV."  "IC.GOV"   however, is grandfathered since it is an existing domain.   Nevertheless, it would be appropriate to provide a copy of the   chartering document to the FNC for the record.  This would ease   future changes to the IC.GOV domain if necessary.FUTURE .GOV REGISTRATIONS   Q.  Top level domains are roughly equivalent to the cabinet-level   agencies identified in FIPS-95-1.  What will happen if non-FIPS-95-1   entities apply for the ".GOV" registration in the future?   A.  The Internic will useRFC 1816 as guidance and will not grant the   ".GOV" to any new entity which is not listed in the FIPS-95-1 or   which has not been granted an exception status by the FNC Executive   Committee.   Q.  Suppose NIH were moved to a new Dept. of Science?  Would our   domain name have to be changed?   A.  NIH.GOV is grandfathered under the existing policy and would not   change.  The "Department of Science" under its own policies may   require you to re-register though.FNC INTENT   Q.  It is unclear how this will policy will facilitate access by the   public to our information, especially since most of the public   doesn't know our organizational structure or that CDC is part of   DHHS/PHS.   A. The policy attempts to avoid confusion as an increasing number of   entities register under the ".GOV" domain and to transfer authority   and responsibility for domain name space to the appropriate agencies   and away from a centralized authority.  For facilitating access,   various tools and capabilities are coming into use on the InternetFederal Networking Council   Informational                      [Page 6]

RFC 1816         U.S. Government Internet Domain Names       August 1995   all the time.  Most of these tools provide a fairly strong search   capability which should obviate most concerns of finding resources   based on domain names.   Q.  Section 1D ofRFC 1816 unfairly constrains the organizations   within the .gov domain in stark contrast toSection 1F which grants   .mil domain organizations full freedom to operate subdomains in any   manner chosen.   A.  The Federal Networking Council has jurisdiction over the ".GOV"   domain names; ".MIL" domain names fall within the jurisdiction of the   Department of Defense.  The .MIL domain has had a written policy   delimiting which DOD agencies get registered directly under .MIL   since about 1987 when the DNS first started to come into use.   Individual agencies under the .MIL domain (e.g., AF.MIL/US Air Force)   are responsible for setting policy within their domains and for   registrations within those domains.  This is exactly equivalent to   the .GOV domain - an individual agency (e.g., Treasury.GOV/Dept of   Treasury) may and should set policy for subregistrations within their   domain.   Q.Section 1B identifies several law enforcement agencies as being   "autonomous" for the purposes of domain registration.  What is the   selection criteria for an "autonomous law enforcement" agency?  For   instance, the Internal Revenue Service (IRS) is responsible for law   enforcement as is the Bureau of Alcohol, Tobacco, and Firearms (ATF).   A.  The selection criteria for "law enforcement agency" is based on   primary mission.  A case could be made for either or both of these   being law enforcement agencies, although the IRS' primary mission is   tax revenue collection and has few armed officers relative to its   size.  An "autonomous" agency is one with mission and role distinct   and (possibly) separate from its containing department.   Unfortunately, 95-1 does not do a good job of identifying   "autonomous" entities.  In the event of problems with registration,   ask the registrar to get a ruling from the FNC.Federal Networking Council   Informational                      [Page 7]

RFC 1816         U.S. Government Internet Domain Names       August 1995ROUTING QUESTIONS   Q.  How will Domain Name Service resolution on the Net work?  Instead   of a root DNS server returning the address of cdc.gov and immediately   directing inquires to our DNS servers, will the root server return a   DNS pointer to DHHS, then DHHS will resolve to PHS, then a fourth DNS   query to get to CDC?  This will add unnecessary traffic to the Net.   (example is host.CDC.PHS.DHHS.GOV)   A.  The answer is based on how you (personally and agency wide)   configure your servers.  First, most servers cache previous answers -   they may have to ask once, but generally remember the answer if they   need it again. Information directly under .GOV will be fairly long-   lived which substantially reduces the requirement to query .GOV   server.  Secondly, multiple levels of the DNS tree MAY reside on the   same server.  In the above example the information for DHHS.GOV,   PHS.DHHS.GOV and CDC.PHS.DHHS.GOV could all reside on the same   server.  Assuming the location of the DHHS.GOV server was not cached,   it would require 2 queries.  Further queries would cache the location   of this server and the servers associated with the domains it serves.   Lastly, the individual agencies may structure their domains as they   please.  CDC could reside directly under DHHS.GOV as CDC.DHHS.GOV   subject to HHS's own policies.Security Considerations   Security issues are not discussed in this memo.Author's Address   Federal Networking Council   4001 N.
