IP Address

[suzuki1]

When asigning the IP address's on a 2 computer network with a switch, is there a certain range of numbers you should use on a network with a certain number of computers, like 192.xxx.xxx.x or can you use any numbers?

Yes, you are supposed to use these ranges:

10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255

In theory, you can use any range you want, from 1.1.1.1 to 254.254.254.254, with the exception of 127.x.x.x which is set aside for testing.

In practice, you want to use the ones that Blstriker listed - They are set aside for use behind firewalls doing NAT and work very well. Others are more risky and generally NOT a good idea unless you have a real need for it.

Another thing you need to consider is the mask. On a small LAN or a segment behind a router on a large LAN, the IP's need to have the same subnet mask scheme to communicate. For instance if one PC had 192.168.1.1 with a mask of 255.255.255.0, and another PC had 192.168.1.2 but a mask of 255.0.0.0, then, without another protocol to use, they would not communicate with each other.
