Every device on a TCP/IP network must have an address
for identification. The IP address is a value consisting of
the network address and the host address on that
network. The value assigned to a network depends on
the number of computers on that network.
The IP address is a 32-bit number. The number is made
up of 4 parts, with each part consisting of 3 digits. One
part of the address identifies the network and another
part of the address identifies the host. The numbers in
the address, which identify the host, are dependent on
the class.
There are 5 classes of IP addresses. Each class represents
a network having a certain number of computers. For
example, a Class C address is given to a network having
between 1 to 255 computers.
The numbers in each part of the code are translated
into binary code, which identifies the network and the
host.
IP addresses are assigned by the Internet Network
Information Center (InterNIC). InterNIC assigns the
network ID. Host IDs are assigned by the network
administrator.
IP Mask Default IP mask for Class A
255.0.0.0
Default IP mask for Class B
255.255.0.0
Default IP mask for Class C
255.255.255.0
Default IP mask for Class D
255.255.255.225
A subnet is a portion of a network that shares a
common address component. On TCP/IP networks,
subnets are defined as all devices whose IP addresses
have the same prefix. For example, all devices whose IP
addresses begin with 133.100.100. are part of the same
subnet. An IP mask allows you to filter IP addresses on a
subnet. When an IP address is configured, the IP mask is
automatically configured according to the Class of the IP
Network.
Note: The default IP mask can be edited.
Default Gateway The default gateway defines where frames will be sent,
if no explicit routing is defined in the routing table.
The default gateway can be an IP address or a WAN
interface. If you choose to use an IP address, enter the
address of the router that will deliver the frames.
Specifying an IP address for the default gateway is done
with shared media, such as LAN interface.
If you choose to use a WAN interface, the connection
to the router is point-to-point. Choose by interface and
enter the interface/DLCI number.
