.uk is the Internet country code top-level domain (ccTLD) for the United Kingdom of Great Britain and Northern Ireland. As of February 2016[update], it is the fifth most popular top-level domain worldwide (after .com, .cn, .de and .net), with over 10 million registrations.
In October 1984, RFC 920 set out the creation of ccTLDs generally using country codes derived from the corresponding two-letter code in the ISO 3166-1 list. GB is the UK's ISO 3166 country code. However, the .uk domain had been created separately a few months before the compilation of the ISO-derived list. Consequently, .gb was never widely used and it is no longer possible to register under that domain.
New registrations directly under .uk have been accepted by Nominet since 10 June 2014 08:00 BST, however there is a reservation period for existing customers who already have a .co.uk, .org.uk, .me.uk, .net.uk, .ltd.uk or .plc.uk domain to claim the corresponding .uk domain, which runs until 07:59 BST on 10 June 2019.
.uk has used OpenDNSSEC since March 2010.
Please have a look at the following SLDs sponsored not directly by the registry. These SLDs may have lower restrictions and prices.
After initiating the transfer in our system, the domain has to be to pushed to our system. Please refer to the transfer instructions for more information. After a transfer, our system syncronizes the owner of the domain from the registry to our system. If possible, you can start an owner change if you want to replace the synced owner. Please start the transfer before the old registrar submits the TAG-CHANGE to Nominet.After the start of a transfer every contact in our system will receive the following instructions:
An Ownerchange is only supported direct at the registry. You cannot change the Owner with our system. An OwnerChange can only be done by the registrant on side of the registry NOMINET directly: https://secure.nominet.org.uk/auth/login.html.
A Restore can be performed in our system up to 90 days after deletion.
