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