This includes any individual network object, such as a server, workstation, printer, or router. You can assign IP addresses to network nodes either statically or dynamically. With a statically assigned address, you specify a fixed address for a given node, and that address never changes unless you manually change it. Static assignment is the option used when the network node must always have the same IP address. Web and FTP servers or devices such as printers that don't support anything other than static assignments are prime examples of devices with statically assigned addresses.

You also can assign IP addresses dynamically through the Dynamic Host Configuration Protocol (DHCP). DHCP enables network nodes to take IP address assignments from a DHCP server automatically at startup. Although dynamic assignment means that IP addresses ...
