The conventional Internet name for a network or computer system, which name consists of a sequence of two or more groups of characters separated by periods; e.g., the "govinst. Com" groups of characters in the host name "www. Govinst. Com", where the ". Com" is the first-level domain name (or top-level domain name,) and the "govinst" characters represent the second level. Note: In the United States, nonprofit organizations are identified (with exceptions) by the suffix ". Org", government entities by ". Gov", educational institutions by ". Edu", commercial organizations are identified by the suffix ". Com", and military bodies by ". Mil". Outside of the United States, domain names contain an ISO-standard country code suffix to indicate the country of origin of the computer or network.
