What is a CNAME

Summary

A CNAME (Canonical Name) points one domain or subdomain to another domain name, allowing you to update one A Record each time you make a change, regardless of how many Host Records need to resolve to that IP address.

Understanding a CNAME


These records point www.example.com to example.com, imap.example.com to mail.example.com, and docs.example.com to ghs.google.com.
The first record allows the domain to resolve to the same server with or without the www subdomain.
The second record allows you to use an alternative subdomain for email hosting an delivery.
The third record allows you to use the docs.example.com subdomain with Google Apps, where you can use Google's document management system. This type of record requires additional configuration with Google.
