A registrant is the individual or organisation that
registers a
domain name with an Internet Service Provider (in Nominet terms, a registrar). They hold the right to use that domain name for a specified period of time, and are bound by Nominet's
terms and conditions of domain name registration.
Nominet provides
Online Services to maintain the registration details of a domain name, along with
how-to guides to help you if you wish to transfer your domain to someone else, or change your registrar.
