As with other ccTLDs in the early days it was originally delegated to an individual by Jon Postel. In time, it passed to Willie Black at the UK Education and Research Networking Association (UKERNA). Originally, domain requests were emailed, manually screened by and then forwarded to the UK Naming Committee before being processed by UKERNA. Membership of this committee was restricted to a group of high-end ISPs who were part of a formal peering arrangement.
The Naming Committee was organised as a mailing list to which all proposed names were circulated. The members would consider the proposals under a ruleset that insisted that all domain names should be very close if not identical to a registered business name of the registrant. Members of the Naming Committee could object to any name, and if at least a small number of objections were received, the name was refused.
Allocation of domain names
Allocations are on a strict first-come, first-served basis to qualified applicants. There are no territorial restrictions: applicants need not have any connection to the UK other than those outlined below for .ltd.uk and other restricted domains.
.co.uk is by far the most used of the domains, followed by .org.uk then .me.uk. .plc.uk and .ltd.uk are only rarely used. The number of new registrations for each of the different .uk domains on a month by month basis can be seen on the Nominet website (www.nominet.org.uk/intelligence/statistics/registration/ Archived July 16, 2012, at the Wayback Machine.)
