Adding an Alias (CNAME) Record

An Alias (CNAME) record maps one host to another. The target host does not have to be within the local domain.

Note: Add a Host (A) record for the source (originating) host before you create the alias.

Caution: Do not use a CNAME alias record for a name-based domain, or an NS or MX record.

To add a CNAME record:

1. In the shortcuts section of the Home page , click Zones (DNS section).
   

   To get to the Home page, click Home on the navigation bar at left.

2. In the Zone List form, locate the zone you want to add a record to, and in the Actions column, click . The Record List form opens. It displays all existing records for the zone.
3. Click Add CNAME Record. The Update Alias (CNAME) Record form opens.
4. In the Alias.domain field, enter the name of the source host you want to map to a second host.
5. In the Target Host Name field, enter the fully qualified name of the host to which the alias will point.

   Note: The host name must be the fully qualified domain name because the entry does not have to be a member of the local domain.

6. Click Add.
