Ptr Record; Adding An Address/Ptr Record - ZyXEL Communications NXC5200 User Manual

The NXC allows you to configure address records about the NXC 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 NXC receives a DNS query for an FQDN
for which the NXC has an address record, the NXC can send the IP address in a
DNS response without having to query a DNS name server.

33.5.4 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.

DESCRIPTION
Type a Fully-Qualified Domain Name (FQDN) of a server. An FQDN starts
with a host name and continues all the way up to the top-level domain
name. For example, www.zyxel.com.tw is a fully qualified domain
name, where "www" is the host, "zyxel" is the third-level domain, "com"
is the second-level domain, and "tw" is the top level domain.
Underscores are not allowed.
Use "*." as a prefix in the FQDN for a wildcard domain name (for
example, *.example.com).
Enter the IP address of the host in dotted decimal notation.
