A standard protocol designed for use in interconnected systems of packet-switched computer
communication networks. The Internet Protocol provides for transmitting blocks of data called

fixed-length addresses. The Internet Protocol also provides for fragmentation and reassembly of
long datagrams, if necessary, for transmission through small-packet networks.
