IP address
A unique 32-bit value that identifies network hosts using TCP/IP. An IP address, or
block of addresses, is assigned upon application to organizations responsible for that

consists of a network number, optional subnetwork number and host number, written
as four numbers separated by periods. Each number can be 0 to 255.
