Adding an Alias (CNAME) record

- Note: If you are not using Ensim Pro as your DNS name server, you do not need to do anything with CNAME records in Ensim Pro; the settings shown in the Appliance Administrator GUI are not used. For more information, see:
  Introduction to DNS and name servers
  Using Ensim Pro as a DNS server

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).

2. In the Zone List form, locate the zone you want to add a record to, and in the Actions column, click . The Host List form opens. It displays all existing records for the zone.

3. In the Add: Record area, click the arrow and choose Alias (CNAME) Record. The Add 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 hostname field, enter the fully qualified name of the host to which the alias will point.

6. 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.
