IP Address

The IP address is one of the two types of addresses each machine has on a TCP/IP network that identifies the machine to its peers on the network. This address also gives peer hosts a notion of where a particular host is located on the network. If you have installed the Solaris operating environment on a machine on a network, you might recall specifying the IP address during the installation process. IP addressing is a significant aspect of TCP/IP and is explained fully in "Designing Your IPv4 Addressing Scheme".
