LABEL DESCRIPTION
Address Record An address record specifies the mapping of a fully qualified domain name
(FQDN) to an IP address. An FQDN consists of a host and domain name and
includes the top-level domain. For example, www.zyxel.com.tw is a fully
qualified domain name, where “www” is the host, “zyxel” is the second-level
domain, and “com.tw” is the top level domain.
# This is the index number of the address record.
FQDN This is a host’s fully qualified domain name.
Wildcard This column displays whether or not the DNS wildcard feature is enabled for this
domain name.
IP Address This is the IP address of a host.

Add Click Add to open a screen where you can add a new address record. Refer to
Table 142 on page 443 for information on the fields.
Name Server Record A name server record contains a DNS server’s IP address. The ZyWALL can
query the DNS server to resolve domain names for features like VPN, DDNS
and the time server.
When the ZyWALL needs to resolve a domain name, it checks it against the
name server record entries in the order that they appear in this list.
A “*” indicates a name server record without a domain zone. The default record
is grayed out. The ZyWALL uses this default record if the domain name that
needs to be resolved does not match any of the other name server records.
A name server record with a domain zone is always put before a record without
a domain zone.
# This is the index number of the name server record.
Domain Zone 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.
From This field displays whether the IP address of a DNS server is from a WAN
interface (and which it is) or specified by the user.
DNS Server This is the IP address of a DNS server.
