Internet Protocol (IP) version 4 (IPv4) is the current standard “IP” protocol used with TCP/IP — Transmission Control Protocol/Internet Protocol — which is the protocol for Internet addressing. In this chapter, you see how IP addresses are structured and broken down into categories and then further broken down for management. None of this information should strike you as too difficult, especially if you have already made your way through Book I.
