Subdomain - Uses

Uses

In the United Kingdom, the third level domain names are standard and branch off of the second-level domains, for example:

.ac.uk - academic (tertiary education, further education colleges and research establishments) and learned societies .co.uk - general use (usually commercial) .gov.uk - government (central and local) .judiciary.uk - courts (to be introduced in the near future) .ltd.uk - limited companies .me.uk - general use (usually personal) .mod.uk - Ministry of Defence and HM Forces public sites .net.uk - ISPs and network companies (unlike .net, use is restricted to these users) .nhs.uk - National Health Service institutions .nic.uk - network use only (Nominet UK) .org.uk - general use (usually for non-profit organisations) .parliament.uk - parliamentary use (only for the UK Parliament and the Scottish Parliament) .plc.uk - public limited companies .police.uk - police forces .sch.uk - Local Education Authorities, schools, primary and secondary education, community education

Subdomains are also used by organizations that wish to assign a unique name to a particular department, function, or service related to the organization. For example, a university might assign "cs" to the computer science department, such that a number of hosts could be used inside that subdomain, such as mail.cs.example.edu or www.cs.example.edu.
