The domain name com is a generic top-leveldomain (gTLD) in the Domain Name System of the Internet.Its name is derived from commercial, indicating its original intended purpose for domains registered by commercial organizations. However eventually the distinction was lost when.com, .org and .net were opened for unrestricted registration. The gTLD com was originally administered by the United States Department of Defense, but is today operated by Verisign. Registrations in com are processed via registrars accredited by ICANN. The registry accepts internationalized domain names. The domain was one of the original top-level domains (TLDs) in the Internet when the Domain Name System was implemented in January 1985, theothers being edu, gov, mil, net, org, and arpa. It has grown into the largest top-level domain.
1985 January net is one of the original top-level domains (the other five being com, edu, gov, mil, and org) despite not being mentioned in RFC 920, having been created in January 1985. As of 2011, it is the third most popular top-level domain, after .com and .de.
The org domain was one of the original top-level domains, with com, edu,gov, mil and net, established in January 1985. It was originally intended for non-profit organizations or organizations of a non-commercial character that did not meet the requirements for other gTLDs. The MITRE Corporation was the first group to register an org domain withmitre.org in July 1985.
1985 In 1985, Kevin Dunlap of DEC significantly re-wrote the DNS implementation. Mike Karels, Phil Almquist, and Paul Vixie have maintained BIND since then. BIND was ported to the Windows NT platform in the early 1990s.
