What does GOV mean in Airport Codes?

gov

The domain name gov is a sponsored top-level domain 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, 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. Other countries typically delegate a second-level domain for this purpose, for example: .gc.ca is the second-level domain for the Government of Canada and all subdomains. 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, and the United States Army's recruitment website.
