The PTR record maps an IP address to a host name. This is the reverse of forward DNS, where instead of getting the IP address for a known host name, you find the host name associated with a known IP address.
Important: Only the server administrator is authorized to view, modify, add, or delete a reverse zone.
To add a reverse pointer:
On the add reverse pointer (PTR) record page, provide the following information:
Note: The reverse lookup pointer record must be of the format "9.8.7.6.in- addr.arpa
".
A reverse pointer is added on the DNS server. The list of DNS pointer records displays the new record.
