Every computer on a Transmission Control Protocol/Internet Protocol (TCP/IP) network is identified by a unique Internet Protocol (IP) address. This also specifies routing information on an Internet network. An IP address is a single value that contains two pieces of information. They are the following: The network ID is the portion of the IP address that identifies a group of computers and other devices located on the same network. The host ID identifies a computer within a particular network ID. A host, or node, is any device that is attached to the network and that uses TCP/IP. Each host on the network uses the network ID and host ID to choose which packets it should receive or ignore. It also uses them to choose the scope of its transmissions. | ||||||||||||||||||||||||||||||||||
