The university itself owns several domains for trademark protection (for instance oxforduniversity.com) or for historical reasons (such as oxford.ac.uk and oxford.edu). College or department usage of these domains is deprecated and new DNS entries will not be permitted; units should normally look to use the ox.ac.uk domain, save for exceptions as described below.
We strongly advise that external domains should be registered through us to simplify administration and to minimise future problems, although this is not mandatory save in the case of .ac.uk domains. IT Services are a member of Nominet and act as a registrar for co.uk, org.uk and other Nominet-managed second-level domains. For most other domain names, IT Services act as an OpenSRS reseller. For certain special cases (such as .museum), we simply register through commercial providers.

- Domains: are “identified by a domain name, and consists of that part of the domain name space that is at or below the domain name which specifies the domain” (p.7, RFC 1034)
- Subdomains: are subsets of a parent domain e.g. unit.ox.ac.uk is subdomain of the parent ox.ac.uk domain.
- Name Servers: “…are server programs which hold information about the domain tree's structure and set information.” (p.5, RFC 1034)
- DNSSEC: “…[adds] origin authentication and integrity protection for DNS data, as well as a means of public key distribution. These extensions do not provide confidentiality.” (p.2, RFC 4033).
- AD Zones: "For a given domain, certain subdomains are used by Microsoft Active Directory 1.The term AD Zones is used to refer specifically to these subdomains but not the parent domain of unit.ox.ac.uk."
