Adding a Reverse Address (PTR) record

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

A Reverse Address (PTR) record specifies a host name for a reverse IP-address-to-host mapping.

Site Administrators acting as Appliance Administrators for their own domains will need to contact their service provider to find out if in-addr.arpa zones have been delegated to their control. If they have not, they can create PTR records, but they will have no effect. They will need to submit any in-addr.arpa changes to their service provider for the changes to take effect.

To add a PTR 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 Reverse Address (PTR) Record. The Add Reverse Address (PTR) Record form opens.

4. In the Hostname.domain field, enter the name of the host to which the IP address should map.

5. In the IP Address field, enter the IP address you want to map to the host.

6. To automatically create a Host (A) record for the host to which the IP address maps, select the Update Address Record check box.

7. Note: If you do not want to create a Host (A) record now, you can manually add a Host (A) record for the forward lookup later.

7. Click Add.
