.gb is a reserved Internet country code top-level domain (ccTLD) for the United Kingdom, derived from Great Britain.
".gb" is the official internet country code that represents the United Kingdom, though it's rarely used because ".uk" is the more common domain choice for British websites. It exists as a reserved address on the internet but matters mainly as a formal designation for the country in the global domain system.

.gb is a reserved Internet country code top-level domain (ccTLD) for the United Kingdom, derived from Great Britain.
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.
