learn how to assign each interface on the router an IP address
with an unique subnet.
Definitions
??
IP Address
– the unique number ID assigned to each
host or interface on a network. IP addresses have the
form xxx.xxx.xxx.xxx.
??
Subnet
– a portion of a network sharing a particular
network address.
??
Subnet mask
– a 32-bit number used to describe which
portion of a Network Address refers to the subnet and
which portion refers to the host. Subnet masks have the
form xxx.xxx.xxx.xxx.
??
Interface
– a network connection
??
IP Interface
– a network connection that is assigned an
IP address.
??
Network Address
– the resulting 32-bit number from a
bitwise logical AND operation performed between an IP
address and a subnet mask.
??
Subnet Address
– another name for network address.
??
Netmask
– another name for a subnet mask.
In a subnetted network, all addresses consist of
two
parts: an IP
address and a subnet mask. The two are used together and one is

The Internet Protocol (IP) was originally designed to allow
communication across network sites comprising the Internet. It
was later adapted to allow routing between subnets within a site
(within an intranet). The IP includes a system by which an
