Posted by grandsnafu [send private reply] at November 27, 2001, 08:46:24 PM If I understand right (probably not), it tells what subnet to look under for other machines connected to your network. So, if you assign IPs of 192.168.1.* to every machine on the network, your subnet is 255.255.255.0. But if you assign IPs of 192.168.*.*, your subnet is 255.255.0.0. Check out google, or any networking webpage. They should have more info. A lot of linux books (if you own any) seem to have a little information, too.

Posted by taubz [send private reply] at December 03, 2001, 05:45:12 PM I don't think that's correct. I believe it's a bitwise mask indicating which bits in your IP determine the subnet. EX: (SubnetMask Logical-And YourIP) = YourSubnet.
