21.6.1 Adding an Address Record
Click
Add
in the
System
screen to open this screen. Use this screen to add an address record.
An address record contains the mapping of a fully qualified domain name (FQDN) to an IP
address. Configure address records about the ZyWALL itself or another device to 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. See
Figure 265
ADVANCED > DNS > Add (Address Record)
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.
Modify
Click a triangle icon to move the record up or down in the list.

Click the delete icon to remove an existing record. A window display asking you
to confirm that you want to delete the record. Note that subsequent records
move up by one when you take this action.
Insert
Click

to open a screen where you can insert a new name server record.
