2146: U.S. Government Internet Domain Names. Federal Networking Council.

This memo provides an update and clarification to RFC 1816. This document describes the registration policies for the top-level domain ".GOV". The purpose of the domain is to provide naming conventions that identify US Federal government agencies in order to facilitate access to their electronic resources. This memo provides guidance for registrations by Federal Agencies that avoids name duplication and facilitates responsiveness to the public. It restricts registrations to coincide with the approved structure of the US government and the advice of its Chief Information Officers. Two documents are recognized as constituting documentation on the US government structure: FIPS 95-1 provides a standard recognized structure into which domain registrations for .GOV and FED.US can fit; and, the US Government Manual [3], a special publication of the Federal Register, provides official documentation of the government structure. The latter document may be subject to more timely updates than the former. Either document is suitable for determining which entities qualify for second-level domain registration within .GOV and FED.US.
