A "CNAME" relates a user-specified 'alias' (a URL) to a fixed/absolute/canonical web address (a URL).
The CNAME is a line of text that is added to the Domain Name System as a piece of data (a database entry).
For example, the CNAME entry
news.example.com CNAME news.myisp.com
relates the alias http://news.example.com to the web-server (and subdomain)
at the "fixed" (canonical) web address http://news.myisp.com.
