The following table describes the labels in this screen.

Table 231 System > DNS > Address/PTR Record Edit

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. For example, zyxel.com.tw is

the domain zone for the www.zyxel.com.tw fully qualified domain name.

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.

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