(ICT) Also known in full as Domain Name Server. A special type of Internet computer which converts a website's domain name into a unique numerical IP Address that identifies the computer where the website is stored. When you try to connect to a website with a domain name such as hull.ac.uk (University of Hull), a request is first made to a name server to resolve this name into an IP address, which is then used to locate the computer where the website is stored and to establish a connection with it.
