Network IP address and Zone Alarm Pro

I updated the zone alarm (freebie) on 18/2 and decided to go for the trial version of Pro. During the installation it gave notification of finding a new network, address 192.168.0.0 on subset 255.255.255.0 (entry type: network)and has given it internet zone rights.
I have two pc's networked via a crossover cable. The host is a Win XP home (192.168.0.1) and the client is a Win 98SE (192.168.0.166). Zone Alarm is only installed on the host computer which acts as the gateway for internet connection sharing.The client (192.168.0.166) is entered in the trusted zone in zone alarm.
Can someone explain where the IP 192.168.0.0 has come from? It is not found when doing a search in Network connections, and it is not recognised in the Ping command.

It is just grouping of IP addresses in a class C with a default subnet mask of 255.255.255.0 .For example 192.168.0.1 to 192.168.0.254(your LAN). If not for this grouping all IP addresses would have to have to be mapped individually for routing. So it is represented by network address of 192.168.0.0.This allows data to be sent to any node by just the network address 192.168.0.0.(for very large LANS networks)This means routing tables only need to know the newtwork address not all nodes(254) on LAN or network.


PS Then there is more info how the router finds node and so on ?
