Canonical Name or CNAME records link an alias name to another canonical domain name. You'll need to configure CNAME records if you want to use URL forwarding to create a custom web address, forward a URL to Google Sites, or forward a naked domain URL, as well as verify your site with your domain name provider. Lastly, you may need to use CNAME records to reset the administrator password if you can’t access the Google Apps control panel because you’ve forgotten the administrator password.
What are CNAME records?
The value of a CNAME record is always a domain name. CNAME records are often used to create subdomains. CNAME records are useful because they allow you to set up an alias to a server IP address with another or "canonical" domain name without having to specify an IP address.
For example, www.example.com can have a CNAME record pointing to example.com. If example.com has an A record configured with an IP address, traffic from www.example.com will be directed to this IP address.
Specifically, you might enable your users to access the Gmail sign-in page with the URL mail.your_domain.com instead of mail.google.com/a/your_domain.com. CNAME records are stored by your domain name provider and therefore must be changed with the provider. See Create CNAME records for instructions.
Please note, creating a CNAME record does not disrupt your current mailflow or affect other services.
