I want to have 150 hosts for the subnet 192.168.100.xxx, starting with the IP address of 192.168.100.100.  Can you tell me what the subnet mask is?


Thanks.

The subnet mask will have to be /24 ie. 255.255.255.0. This will however include hosts 192.168.100.1 -> 254 which is more than you want. If you want 150 hosts you have to use a class C subnet mask because the next one down ie. 255.255.255.128 only covers 126 hosts.
