A DHCP (Dynamic Host Configuration Protocol) server can assign your ZyXEL 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 is an improvement over version 1, but IGMP version 1 is still in wide 
use. IGMP version 3 supports source filtering, reporting or ignoring traffic from specific 
source address to a particular host on the network.

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.

Use this screen to configure your LAN settings. Click Interface Setup > LAN to display the 
following screen.
Follow these steps to configure your LAN settings.

1 Enter an IP address into the IP Address field. The IP address must be in dotted decimal 

notation. This will become the IP address of your ZyXEL Device.

2 Enter the IP subnet mask into the IP Subnet Mask field. Unless instructed otherwise it 

is best to leave this alone, the configurator will automatically compute a subnet mask 
based upon the IP address you entered.

3 Click SAVE to save your settings.
