Definition of Registrar

An organisation which retains a register of internet- domainnames, who owns them, and where they can be found. Domains under the most popular- TLDs such as .com, .net and .org can be registered with a number of different competing registrars, but you only need to register with one of them. National domains such as .uk usually have only one registrar.
