IP Screen

This chapter discusses how to configure IP on the ZyXEL Device.

10.1  Factory Ethernet Defaults

The Ethernet parameters of the ZyXEL Device are preset in the factory with the following 
values:

1

IP address of 192.168.1.2

2

Subnet mask of 255.255.255.0 (24 bits)

These parameters should work for the majority of installations.

10.2  TCP/IP Parameters

10.2.1  WAN IP Address Assignment

Every computer on the Internet must have a unique IP address. If your networks are isolated 
from the Internet (only between your two branch offices, for instance) you can assign any IP 
addresses to the hosts without problems. However, the Internet Assigned Numbers Authority 
(IANA) has reserved the following three blocks of IP addresses specifically for private 
networks.

You can obtain your IP address from the IANA, from an ISP or have it assigned by a private 
network. If you belong to a small organization and your Internet access is through an ISP, the 
ISP can provide you with the Internet addresses for your local networks. On the other hand, if 
you are part of a much larger organization, you should consult your network administrator for 
the appropriate IP addresses.
