The IP Register database allows IT staff in Colleges and Departments to manage DNS registrations for their IP address space.

The Domain Name System (DNS) is a necessary part of internet connectivity. It is the global database that maps host names and service names to IP addresses.

The IP Register database is the University of Cambridge's database of host name, service name, net block, and IP address allocations. Our part of the DNS (principally under the domain) is provisioned from the IP Register database.
