Configuring The Dns Screen - ZyXEL Communications ZyWall USG 2000 User Manual

Chapter 46 System
• The ISP tells you the DNS server addresses, usually in the form of an
information sheet, when you sign up. If your ISP gives you DNS server
addresses, manually enter them in the DNS server fields.
• If your ISP dynamically assigns the DNS server IP addresses (along with the
ZyWALL's WAN IP address), set the DNS server fields to get the DNS server
address from the ISP.
• You can manually enter the IP addresses of other DNS servers.

46.5.2 Configuring the DNS Screen

Click System > DNS to change your ZyWALL's DNS settings. Use the DNS screen
to configure the ZyWALL to use a DNS server to resolve domain names for
ZyWALL system features like VPN, DDNS and the time server. You can also
configure the ZyWALL to accept or discard DNS queries. Use the Network >
Interface screens to configure the DNS server information that the ZyWALL
sends to the specified DHCP client devices.

DESCRIPTION
This record specifies the mapping of a Fully-Qualified Domain Name
(FQDN) to an IP address. An FQDN consists of a host and 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.
This is the index number of the address/PTR record.
This is a host's fully qualified domain name.
