  1. gb

    .gb is a reserved Internet country code top-level domain for the United Kingdom. The domain was introduced with RFC 920 in October 1984 that set out the creation of ccTLD generally using country codes derived from the corresponding two-letter code in the ISO 3166-1 list. However, the .uk domain had been created separately a few months before the compilation of this list. Consequently, .gb was never widely used. It is no longer possible to register under this domain. .gb was used for a number of years, mainly by British government organisations and commercial e-mail services using X.400-based e-mail infrastructure. This simplified translating between DNS domains and X.400 addresses, which used "GB" as a country code. With the demise of X.400 e-mail and IANA's general aim of one TLD per country, use of .gb declined; the domain remains in existence, but it is not open to new subdomain registrations. One .gb subdomain still exists in the DNS:, belonging to Her Majesty's Government's former Defence Research Agency, and has three known hostnames remaining:, and
