Domain Names

A domain name locates a trust or other health entity on the internet, or intranet or the NHS N3 network. For example, the domain name 'www .yourorg.nhs.uk' (or nww for the N3 network).

This locates an Internet address for "yourorg.nhs.uk" at a specific internet protocol (IP) address and a particular host server named "www". Together, "www.yourorg.nhs.uk" constitutes a fully-qualified domain name (FQDN).
