Chapter 7 LAN Setup

AMG1302-T10A User’s Guide

Subnet masks determine the maximum number of possible hosts on a network. You can also use 

subnet masks to divide one network into multiple sub-networks.

A DHCP (Dynamic Host Configuration Protocol) server can assign your Device an IP address, subnet 

mask, DNS and other routing information when it's turned on.

RIP (Routing Information Protocol) allows a router to exchange routing information with other 

routers.

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) 

or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of 

hosts on the network - not everybody and not just 1.

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership 

in a Multicast group - it is not used to carry user data. There are three versions of IGMP. IGMP 

version 2 and 3 are improvements over version 1, but IGMP version 1 is still in wide use.

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and 

vice versa. The DNS server is extremely important because without it, you must know the IP 

address of a networking device before you can access it.

See 

 for technical background information on LANs.

Find out the MAC addresses of your network devices if you intend to add them to the DHCP Client 

List screen.

Use this screen to set the Local Area Network IP address and subnet mask of your Device. Click 
Network > LAN

 to open the IP screen. 

Follow these steps to configure your LAN settings.
