The Domain Name Service provides the name to address mapping function for the internet. It exists as a distributed database across the internet maintained by a process of delegated authority. The Oxford names servers are authorised to store and supply naming information about computers in the ox.ac.uk domain. OUCS manages the Oxford name servers, but authorises local network administrators to perform updates to their particular subnetworks.
