an IP address is a 32-bit number
that identifies each sender or
receiver of information that is
sent in packets across the
Internet.
The IP address is usually
expressed as four decimal
numbers, each representing eight
bits, separated by periods. This is
sometimes known as the dot
address and, more technically, as
dotted quad notation
