There are two types of IP addresses:
•
Dynamic – A dynamic IP address changes. Dynamic IP addresses are
randomly assigned to computers by an IP address server as the computer
needs it. Usually there is a particular range (or scope) of IP addresses that
your network uses. With dynamic IP addressing, a computer can have a
different IP address each time it connects to the network. Other devices need
to know the computer’s IP address so that they can communicate with it. The
IP address server manages the assignment of IP addresses to the workstations.

•
Static – A static (or fixed) IP address does not change. It is assigned to a
computer permanently. The computer has the same IP address every time it
connects to the network and is known to other devices on the network by that
IP address. Because the Instant Internet unit on your network is also the
gateway to the Internet, it must have a LAN-side static IP address.

Understanding DHCP servers
The IP address server that manages the dynamic IP addresses is called a DHCP
(Dynamic Host Configuration Protocol) server. You can set up Instant Internet to
be your network’s DHCP server and let it do the work of assigning IP addresses to
the workstations on your network as needed. This is the recommended
configuration.

When you set up the Instant Internet unit as a DHCP server, configure each of
your workstations to get their new IP addresses assigned by Instant Internet. Refer

If you already have a DHCP server, you must configure the DHCP server to use
the Instant Internet unit as the gateway and DNS proxy for the workstations. Refer
