DNS and IP addressing

The University Hostmaster provides the following services:

  • the IP Register database, which manages the contents of the DNS for most of cam.ac.uk and the University's IP address space

  • the Managed Zone Service, which is our DNS domain registration and hosting service for non-cam.ac.uk domains

  • DNS servers, including resolvers for use by devices on the University Data Network (UDN), and authoritative servers on site and off site that host University domain names

  • DHCP servers that are integrated with the IP Register database.

Our DNS website also provides news about DNS in Cambridge, information about how we block malicious domain names, configuration advice for stealth secondary servers on the UDN and links to some of our open source software.

Domain names

UIS provides advice and technical support for registering DNS domain names.
The process for registering a domain name depends on the name.

IP address ranges

This section includes a full list of the IPv4 and IPv6 address ranges used on the UDN for connecting the University, its constituent Colleges and other affiliated organisations.

IPv6 at Cambridge

UIS is gradually enabling its services with support for Internet Protocol version (IPv6) – the next generation of TCP/IP, the network communications protocol that is used to route traffic across the global internet. The version used predominantly on the internet, which most people are familiar with, is version 4.

This section includes an explanation of some of the key differences between the two protocols and details on how IPv6 will be implemented on the UDN.
