An IP address is a 32 bit number that uniquely identifies
a computer (i.e. an networking interface) on your network or the
Internet.
This number is commonly represented in dotted quad" format.
Each octet (8 bits) is represented as a decimal number.
Dots are used as octet separators (e.g. 10.0.0.138).
Historically, an IP address consists of two parts: a network part
and a host part.
The network part identifies the network on which a PC/workstation
resides. The host part identifies a particular PC/workstation on a
given network.
The dividing line between the network part and the host part can
be derived from the netmask or subnet mask.
The 1 bits in the Subnet Mask represent the contiguous leading
bits of the IP address that has network significance.
