==Background==
In 1984, [[Jon Postel]] and [[Joyce Reynolds]] published RFC 920 which introduced the initial top level domain names (TLDs) describing their categories and general purposes. These include: .arpa, the current internet host during that time; .gov (government) .edu, (education) .com, (commercial) .mil (military) .org (organization) and the two-letter code (alpha-2) [[ISO]]-3166-1 list which represents the names of countries.<ref>[http://www.ietf.org/rfc/rfc920.txt RFC 920]</ref>
