Once the domain is registered

All United Kingdom (Not in use) domain names registered with us are stored on our international server. Domains registered with us are automatically provided with their own under-construction page - this notifies potential registrants that the name has been acquired and is now registered. The under-construction page is offered free of charge and may be used indefinitely.

It is possible for Web and/or Mail forwarding to be provided for United Kingdom (Not in use) domains.

Domain transfer/release fees are charged are by a majority of registrars, but BB Online make no charge to transfer a domain to another United Kingdom (Not in use) domain name registrar.


Fallen into disuse in favour of .uk


Important Note:
Some domain names may be classified by the registry as a premium domain name and will command a higher price. If you request a premium domain name we will contact you before completing your order.

In addition, the registry may at any time reserve domain names from registration or the sale may be restricted to comply with ICANN requirements.

.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):, belonging to Her Majesty's Government's former Defence Research Agency.
