B: IP A
DDRESSING
This type of IP Address operates on a subnet mask of ‘255.255.255.0’.
See Table 1 for an example about how a network with three PCs and a Cable/DSL
Gateway might be configured.
Table 1
IP Addressing and Subnet Masking
Type 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 Table 2 for an example about how a network (only four PCs represented) and
a Cable/DSL Gateway might be configured.
Table 2
IP Addressing and Subnet Masking
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 Cable/DSL Gateway 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
®
95, 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.
