The net.uk Second Level Domain is a closed domain intended for NIC (Network Information Centre), NOC (Network Operations Centre), and other administrative use, and users are required to be Internet Service Providers (ISPs).

Because it is a closed domain registrants must pass, and continue to pass the tests set out in the rules (both generally and the specific clause for this Second Level Domain).

In addition to these tests, the use of the domain name is restricted to personal use for the administrative functions.  It should not be used for any external functions, such as email for customers.  Such use can lead to cancellation of the domain name.  The tests are summarised as follows:

• the applicant is listed as a local internet protocol (IP) address registry with a regional IP address registry; or
• has an Autonomous System containing hosts in the United Kingdom that is listed with a regional IP address registry and that is continuously or at all reasonable times reachable from major Internet exchange points.

NOTE: Applications are reviewed by a member of staff and so will take longer to issue than the fully automatic co.uk or org.uk domains.
