Adding or Editing CNAME Records

Date Submitted: 11-28-2012

A CNAME (Alias) record points to an A (Host) record. You can create multiple CNAME records and point them to an A record. The most common CNAME records are the subdomains www and ftp.

CNAME records make your DNS data easier to manage. If you change the IP address of an A record, all CNAME records pointed to that A record automatically follow the new IP address. The alternative solution, multiple A records, is not as simple as using CNAME records.

You can click Restore Defaults in the CNAME (Alias) section of the Zone File Editor to restore the default MX records for your domain name. For more information, see Restoring a Domain Name's Zone File Records.
