In Pakistan domain names (.pk domains) are registered by an entity called PKNIC.
Policy for Registration of Domain Names
PKNIC requires the applicant who wants to register a domain name to agree to the following:
1. The registration of a domain name is a listing service. The listing service of names within the .PK delegated name space is undertaken on a First Come - First Served basis (except in cases where it infringes upon a registered tradename), moderated by the .PK domain's administration policies as determined by the delegated authority. The registration function does not trade in, or license in any way any entity (including the listing requesting entity) to trade in the requested name.
