DNS provides the name to address mapping function for the internet
DNS exists as a distributed database across the Internet maintained by a process of delegated authority. The Oxford name servers are authorised to store and supply naming information about computers in the ox.ac.uk domain. IT Services manages the Oxford name servers, but authorises local network administrators to perform updates to their particular subnetworks.
The Interface for Hosts Update is the preferred mechanism for updating the Oxford University hosts database. (Zones other than ox.ac.uk and related reverse-DNS zones are still managed manually; please mail firstname.lastname@example.org to request changes in such zones.) The following links give access to various elements of the University's DNS Service:
