37.6.3 (IPv6) Address Record
An address record contains the mapping of a Fully-Qualified Domain Name (FQDN) to an IP address.
The Zyxel Device allows you to configure address records about the Zyxel Device itself or another
device. This way you can keep a record of DNS names and addresses that people on your network may
use frequently. If the Zyxel Device receives a DNS query for an FQDN for which the Zyxel Device has an
address record, the Zyxel Device can send the IP address in a DNS response without having to query a
DNS name server.
37.6.4 PTR Record
A PTR (pointer) record is also called a reverse record or a reverse lookup record. It is a mapping of an IP
address to a domain name.

Click the

#
This the index number of the service control rule. The ordering of your rules is important as
rules are applied in sequence.
The entry with a hyphen (-) instead of a number is the Zyxel Device’s (non-configurable)
default policy. The Zyxel Device applies this to traffic that does not match any other
configured rule. It is not an editable rule. To apply other behavior, configure a rule that traffic
will match so the Zyxel Device will not have to use the default policy.
Zone
This is the zone on the Zyxel Device the user is allowed or denied to access.
Address
This is the object name of the IP address(es) with which the computer is allowed or denied to
send DNS queries.
Action
This displays whether the Zyxel Device accepts DNS queries from the computer with the IP
address specified above through the specified zone (
Accept
) or discards them (
Deny
).
