Reverse Lookup Zones
Reverse lookup zones can be configured in Network>Inbound Access>DNS Settings.
Reverse lookup refers to performing a DNS query to find one or more DNS names associated with a given
IP address.
The DNS stores IP addresses in the form of specially formatted names as pointer (PTR) records using
special domains/zones. The zone is in-addr.arpa.
To enable DNS clients to perform a reverse lookup for a host, perform two steps:
Create a reverse lookup zone that corresponds to the subnet network address of the host.
In the reverse lookup zone, add a pointer (PTR) resource record that maps the host IP address to
the host name.
Click the New Reverse Lookup Zone button and enter a reverse lookup zone name. If you are
delegated the subnet 11.22.33.0/24, the Zone Name should be 33.22.11.in-arpa.addr. PTR
records for 11.22.33.1, 11.22.33.2, ... 11.22.33.254 should be defined in this zone where the host
IP numbers are 1, 2, ... 254, respectively.
