CNAME Records

CNAME allows a machine to be known by one or more hostnames.  There must always be an A record first, and this is known as the canonical or official name.  For example:  A

Using CNAME, you can point other hostnames to the canonical (A record) address.  For example:  CNAME  CNAME  CNAME

CNAME records make it possible to access your domain through,, etc.  Without a proper CNAME record, you will not be able to connect to your server using such addresses.

Entering a CNAME record

If we wanted to point to, we could enter the record in two ways:

home  CNAME
The first method allows you to simply enter the subdomain.  Do not put a period after the subdomain name.  CNAME
The second method requires you to enter the entire hostname, followed by a period.
