Chapter 5 System Screens

This chapter provides information on the System screens.

The Ethernet parameters of the G-560 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)
• Encryption: Disable

These parameters should work for the majority of installations.

Every computer on the Internet must have a unique IP address. If your networks are isolated 
from the Internet, for instance, only between your two branch offices, 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.

Table 6   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

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.
