E: IP Addressing
Each TCP/IP node on a network host has a unique IP address. This address provides the
information needed to forward packets on the local network and across multiple networks
if necessary.
IP addresses are specified as x.x.x.x, where each x is a number from 1 to 254, for example,
192.0.1.99. The Device Server must be assigned a unique IP address to use network
functionality.
IP addresses contain three pieces of information: the network, the subnet mask, and the
host.
