Selecting the Type and Method of IP Address Configuration ‹‹ What is an IP address? The IP address is an identification number allocated to computers and other devices connected to an IP network. An IP address is an address for use on a network. There are two types of IP address: IPv4 and IPv6. • IPv4 address The IPv4 address consists of four fields, such as "192.168.0.113". The first three fields (192.168.0) are fixed, and the last one (113) is variable. 192. 168. 0. 113 DCT046 1 192. 168. 0. 111 2 3 4 192. 168. 0. 112 192. 168. 0. 113 192. 168. 0. 114 DCT150 1.
