CNAME record

(Canonical NAME record) A statement in a DNS database (zone file) that assigns an alias to the true name (canonical name) of a local or remote server. It is used to direct multiple URLs, such as www.xyz.com and support.xyz.com to a single IP address, as well as to redirect users to sites after their URLs change or are abandoned.
