Typ e Two

In larger networks, where there are more devices, the IP address

of ‘192.168.100.8’ is, again, split into two parts but is structured

differently:

■ Part one (‘192.168’) identifies the network on which the

device resides.

■ Part two (‘.100.8’) identifies the device within the network.

This type of IP Address operates on a subnet mask of

‘255.255.0.0’.

See Ta ble 4

for an example about how a network (only four PCs

represented) and a Secure Router might be configured.

How does a Device Obtain an IP Address and

Subnet Mask?

There are three different ways to obtain an IP address and the

subnet mask. These are:

■ Dynamic Host Configuration Protocol (DHCP) Addressing

■ Static Addressing

■ Automatic Addressing (Auto-IP Addressing)

DHCP Addressing

The Secure Router contains a DHCP server, which allows

computers on your network to obtain an IP address and subnet

mask automatically. DHCP assigns a temporary IP address and

subnet mask which gets reallocated once you disconnect from

the network.

DHCP will work on any client Operating System such as

Windows

XP, Windows 98 or Windows NT 4.0. Also, using

DHCP means that the same IP address and subnet mask will

never be duplicated for devices on the network. DHCP is

particularly useful for networks with large numbers of users on

them.

Static Addressing

You must enter an IP Address and the subnet mask manually on

every device. Using a static IP and subnet mask means the

address is permanently fixed.
