ZyWALL USG 2000 User’s Guide

third-level domain, “com” is the second-level domain, and “tw” is the top level 
domain.

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

46.5.4  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.

46.5.5  Adding an Address/PTR Record 

Click the Add icon in the Address/PTR Record table to add an address/PTR 
record.

Figure 466   

System > DNS > Address/PTR Record Edit

The following table describes the labels in this screen. 

 

46.5.6  Domain Zone Forwarder 

A domain zone forwarder contains a DNS server’s IP address. The ZyWALL can 
query the DNS server to resolve domain zones for features like VPN, DDNS and 
the time server. A domain zone is a fully qualified domain name without the host.

LABEL

DESCRIPTION

FQDN

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.

IP Address

Enter the IP address of the host in dotted decimal notation.
