8.3 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 New Dynamic

DNS Entry.
