A reverse zone is an entry in the DNS zone file that enables the translation of IP addresses to host names. You can add reverse zones in DNS through the server control panel. A special Pointer (PTR)-record type is used to store reverse DNS entries.
Important: Only the server administrator is authorized to view, add, or remove a reverse zone.
To add a reverse zone:
Note: The name of a PTR-record is the IP address with its segments reversed along with the special domain name ".in-addr.arpa
". For example, the reverse lookup record for the IP address 5.6.7.8
would be stored as a PTR-record for "8.7.6.5.in- addr.arpa
".
A reverse zone is created.
