6.1 Overview
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is usually located in one immediate area such as a building or floor of a
building.
The LAN screens can help you configure a LAN DHCP server and manage IP addresses.
6.1.1 What You Need To Know
The following terms and concepts may help as you read this chapter.
6.1.1.1 About LAN IP Address
Similar to the way houses on a street share a common street name, so too do computers on a
LAN share one common network number. This is known as an Internet Protocol address.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your LTE Device will
compute the subnet mask automatically based on the IP address that you entered. You don't
need to change the subnet mask computed by the LTE Device unless you are instructed to do
otherwise.
