The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its location, or address, on the network. This applies to both the Internet and LAN connections.

NOTE: Since the Router is a device that connects two networks, it needs two IP addresses—one for the LAN, and one for the Internet. In this User Guide, you’ll see references to the “Internet IP address” and the “LAN IP address.”

NOTE: Since the Router uses NAT technology, the only IP address that can be seen from the Internet for your network is the Router’s Internet IP address. However, even this Internet IP address can be hidden on the Internet by suppressing PING response.

There are two ways of assigning IP addresses to your network devices.

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with dedicated network devices such as server PCs or print servers. Since a user’s PC is moving around in a network and is being powered on or off, it does not require a dedicated IP address that could be a precious resource in your network.
