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
