DHCP
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
RIP (Routing Information Protocol) allows a router to exchange routing information with
other routers.
Multicast
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
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
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.

8.2 The LAN Screen
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.
