DNS Settings

The second section of the Advanced window is the DNS (Domain Name System)

settings section, which includes “Dynamic DNS” and “DNS Server.”

8.3a

Dynamic DNS

Dynamic DNS creates a dynamic IP address that is aliased to a static hostname,

allowing a computer on the network to be more easily accessible from the

Internet. Typically, when connecting to the Internet, the service provider assigns

an unused IP address from a pool of IP addresses, and this address is used only

for the duration of a specific connection. Dynamically assigning addresses

extends the usable pool of available IP addresses, while maintaining a constant

domain name. This allows the user to access a device (a camera, for example)

from a remote location, since the device will always have the same IP address.

When using Dynamic DNS, each time the IP address provided by the ISP

changes, the DNS database changes accordingly to reflect the change. In this

way, even though the IP address of the computer changes often, its domain

name remains constant and accessible.

Setting up Dynamic DNS

To set up Dynamic DNS on the FiOS Router, click

Dynamic DNS

in the Advanced

screen. When the “Dynamic DNS” screen appears, click

8.3b

DNS Server

The Domain Name System (DNS) translates domain names into IP addresses,

and vice versa. The FiOS Router’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

can immediately communicate with this computer using either its name or its

IP address.

The FiOS Router’s DNS also provides the following services:

shares a common database of domain names and IP addresses with the

•

DHCP server;

supports multiple subnets within the local network simultaneously;

•

automatically appends a domain name to unqualified names;

•

allows new domain names to be added to the database using the FiOS

•

Router’s GUI;

permits a computer to have multiple host names;

•

and permits a host name to have multiple IPs (needed if a host has multiple

•

network cards).

The DNS server does not require configuration. However, the list of computers

known by the DNS can be viewed or a new computer can be added to the list.
