Important: When entering your search string don't write “www” or the United Kingdom (Not in use) domain type, ie. “.gb”. Therefore to search “www.bb-online.gb” enter “bb-online” and nothing else.
The only letters allowed within a domain name are: a b c d e f g h i j k l m n o p q r s t u v w x y z - 0 1 2 3 4 5 6 7 8 9. Spaces are NOT ALLOWED.
.gb registration your United Kingdom (Not in use) domain, click here!.gb is a reserved Internet country code top-level domain (ccTLD) for the United Kingdom. Introduced at the same time as the UK's other top-level domain (.uk), it was never widely used. It is no longer possible to register under this domain.
The rule in the Domain Name System is that a top-level domain for a country is derived from the corresponding two-letter code in the ISO 3166-1 list. Accordingly the correct code for the United Kingdom of Great Britain and Northern Ireland is GB, and the .gb top-level domain was therefore delegated.
The pre-existing JANET Name Registration Scheme had used "UK" as a country code, so the UK also applied to Jon Postel of IANA for the .uk TLD. This was granted, and all UK domain names are now issued as .uk, rather than .gb.
.gb was used for a number of years, mainly by UK 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 (as of 2008): dra.hmg.gb, belonging to Her Majesty's Government's former Defence Research Agency.
