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.
To Access the Zone File Editor
- Log in to your Account Manager.
- Next to Domains, click Launch.
- From the DNS menu, select DNS Manager, and then click Edit Zone for the domain name you want to update.
To Add a CNAME Record
- Go to the Zone File Editor for the domain name you want to update.
- Click Add New Record. The Add DNS Record window displays.
- From the Record type list, select CNAME (Alias).
- Complete the following fields:
- Enter an Alias Name — Enter the subdomain name for the alias assignment. For example, type www.
- Points to Host Name — Enter the host name you want the alias to point to. For example, type @ to map the alias directly to your domain name.
- TTL — Select how long the server should cache the information.
- Click OK.
- Click Save Zone File, and then click OK. The new CNAME record displays in the CNAME (Alias) section.
To Edit a CNAME Record
- Go to the Zone File Editor for the domain name you want to update.
- In the CNAME (Alias) section, click the CNAME record you want to edit.

NOTE: 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.
