The domain name gov is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. The name is derived from government indicating its restricted use by government entities in the United States. The gov domain is administered by the General Services Administration (GSA) an independent agency of the United States federal government.

The U.S. is the only country that has a government-specific top-level domain in addition to its country-code top-level domain. This is a result of the origins of the Internet as a U.S. federal government-sponsored research network (see ARPANET and National Science Foundation Network). Other countries typically delegate a second-level domain for this purpose.

Some U.S. federal agencies use fed.us rather than gov. The Department of Defense and its subsidiary organizations use the mil sTLD. Some U.S. governmental entities use other domains such as com domains by the United States Postal Service (which uses both usps.gov and usps.com for the same website although it only advertises the com address) and the United States Army's recruitment website (goarmy.com this trend is repeated at the recruitment websites of the other branches of the U.S. military).

Additionally some technically private organizations having some formal association with the federal government make use of gov such as the Federal Reserve System (federalreserve.gov).

All governments in the U.S. are allowed to apply for delegations in gov such as atlantaga.gov for the city of Atlanta loudoun.gov for the county of Loudoun Virginia and georgia.gov for the U.S. state of Georgia. This was not always true; under an earlier policy only federal agencies were allowed to use the domain and agencies beneath cabinet level were required to use subdomains of their parent agency. There is a lack of consistency in addresses of state and local government sites with some using gov some us some using both (the Commonwealth of Pennsylvania uses www.pa.gov www.pennsylvania.gov and www.state.pa.us for the same web site) and still others in com org or other TLDs.

Use of the gov domain is restricted to governments entities. According to GSA guidelines this includes U.S. Governmental departments programs and agencies on the federal level; federally recognized tribes (referred to by the GSA as Native Sovereign Nations which must use the suffix -NSN.gov); State governmental entities and programs; cities and townships represented by an elected body of officials; counties and parishes represented by an elected body of officials; and U.S. territories.1

To register a gov domain a letter of authorization must be submitted to the GSA. For federal agencies the authorization must be submitted by cabinet-level chief information officer (CIO). For state governments authorization from the governor or state CIO is required. Domain names for cities require authorization from the mayor or equivalent official; for counties authorization may be submitted by county commissioners or equivalent officials or by the highest-ranking county official.3 For Native Sovereign Nations the authorization must come from the Bureau of Indian Affairs.4 Naming conventions

The GSA provides guidelines for naming of second-level domains such as those used by state and local governments. For states the domain name must include the full state name or postal abbreviation and the abbreviation must not be obscured by inclusion in a larger word. For example invalid.gov for Idaho would be an unacceptable domain name. For local governments the domain name must include the state name or abbreviation. However many .gov domain names (such as boston.gov and seattle.gov) do not conform to the naming convention because they were already registered before the GSA enacted this policy. 5 Policy This section requires expansion. Policy regarding the gov domain is laid out in 41 CFR Part 102-173 a Final Rule promulgated by the GSA in the Federal Register on March 28 2003.6 States in GOV As of November 2009 all states in the U.S. have operational domains in gov: Alabama al.gov and alabama.gov Alaska alaska.gov Arizona az.gov Arkansas ar.gov and arkansas.gov California ca.gov and california.gov Colorado colorado.gov Connecticut ct.gov Delaware Delaware.gov Florida florida.gov (redirects to myflorida.com) Georgia georgia.gov and ga.gov Guam guam.gov Hawaii hawaii.gov (redirects to ehawaii.gov) Idaho idaho.gov Illinois Illinois.gov Indiana in.gov Iowa iowa.gov Kansas ks.gov and kansas.gov Kentucky ky.gov and kentucky.gov Louisiana louisiana.gov Maine maine.gov Maryland maryland.gov Massachusetts mass.gov Michigan michigan.gov Minnesota mn.gov (redirects to state.mn.us) Mississippi mississippi.gov Missouri mo.gov Montana mt.gov and montana.gov Nebraska nebraska.gov Nevada nv.gov New Hampshire nh.gov and visitnh.gov New Jersey nj.gov and newjersey.gov New Mexico newmexico.gov New York ny.gov North Carolina nc.gov and northcarolina.gov North Dakota nd.gov Ohio ohio.gov Oklahoma ok.gov Oregon oregon.gov Pennsylvania pa.gov and pennsylvania.gov Puerto Rico pr.gov Rhode Island ri.gov South Carolina sc.gov South Dakota sd.gov Tennessee tennessee.gov and tn.gov Texas texas.gov Utah utah.gov Vermont vermont.gov Virginia virginia.gov Washington wa.gov and washington.gov West Virginia wv.gov Wisconsin wisconsin.gov Wyoming wyoming.gov The District of Columbia follows this trend with dc.gov See also .gov.sg References "Eligibility Requirements".
