A Canonical Name Record (CNAME) serves to make one domain an alias of another domain. The CNAME record is often used to associate new subdomains with the DNS records of an existing domain.
A CNAME record consists of the following three fields:
-
Host
-
Points To – The canonical name, entered as an FQDN, with or without a trailing dot. This hostname must correctly resolve to an IP address, or the CNAME will not function. Additionally, a wildcard ( * ) can be used at the beginning of canonical name. Some examples include:
-
For example: targetname.example.com or targetname.example.biz.
-
-
TTL
