DNS

We run a complete domain name service (DNS) which assigns a permanent fully-qualified domain name (FQDN) (*) in the .inf.ed.ac.uk domain to any machine on our network which has been assigned a fixed IP address. We do not run a dynamic DNS service, so we cannot give a permanent FQDN to any machine which is using a dynamically-assigned IP address.

We run a 'resolver' at each site, for the benefit of self-managed machines. The address(es) for this service will be configured by DHCP as appropriate.

Note: Users of self-managed machines in the Informatics Forum or in Appleton Tower should always configure such machines to acquire their complete TCP/IP configuration via DHCP. Doing so is the only way such machines can be guaranteed to acquire correct DNS server configuration, correct IP routing configuration etc.

(* A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or host, on the Internet. The FQDN consists of two parts: the hostname and the domain name. For example, an FQDN for a hypothetical server might be fred.inf.ed.ac.uk. The hostname is fred, and the host is located within the domain inf.ed.ac.uk.)
