DNS
Domain Name System. The system used by machines on a network to associate standard IP ad-
dresses (such as 198.93.93.10) with hostnames (such as www.example.com). Machines normally
get the IP address for a hostname from a DNS server, or they look it up in tables maintained on
their systems.
DNS alias
A DNS alias is a hostname that the DNS server knows points to a different host-specifically
a DNS CNAME record. Machines always have one real name, but they can have one or more
aliases. For example, an alias such as www. yourdomain.domain might point to a real machine
called realthing. yourdomain.domain where the server currently exists.
