LAN
This chapter describes how to configure LAN settings.
5.1 LAN Overview
A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. Use the LAN screen to configure the ZyXEL Device’s IP address to be on your network.
5.1.1 Factory LAN Defaults
The LAN parameters of the ZyXEL Device are preset in the factory with the following values:
•IP address of 192.168.1.2
•subnet mask of 255.255.255.0 (24 bits)
5.1.2IP Address
Every computer on your network must have a unique IP address. The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.
Table 19 Private IP Address Ranges
10.0.0.0- 10.255.255.255
172.16.0.0- 172.31.255.255
192.168.0.0 - 192.168.255.255
The ZyXEL Device’s IP address can be assigned manually (a static or ‘fixed’ IP address) or by a DHCP server on your network.
"Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.
