15.2 Configuring a DNS Server
The DNS Server icon allows you to manage the device's Domain Name System
(DNS) server. The DNS server does not require configuration. However, you can view the
list of computers known by the DNS, edit the host names or IP addresses of computers in
the list, or manually add a new computer to the list.
DNS provides a service that translates domain names into IP addresses and vice versa.
The device's DNS server is an auto-learning DNS, which means that when a new computer
is connected to the network, the DNS server learns its name and automatically adds it to
the DNS table. Other network users may immediately communicate with this computer
using either its name or its IP address.
The device's DNS server also provides the following functionalities:

Shares a common database of domain names and IP addresses with the DHCP
server.

Supports multiple subnets within the LAN simultaneously.

Automatically appends a domain name to unqualified names.

Allows new domain names to be added to the database using the device's Web
interface.

Permits a computer to have multiple host names.

Permits a host name to have multiple IPs (needed if a host has multiple network
cards).
