Just a note on allocating subnets (using a single netmask): 1) Pick an appropriate subnet mask (for then example: 255.255.255.0 for a B). 2) Then allocate the subnets by changing the high order bits of the subnet field (ie: X.X.128 first, then 64, 192, 32, 96, ...) 3) Allocate hosts within a subnet using the low order bits of the host field (ie: 1, 2, 3). Why? Because what you think now might be the right subnet mask may not be the right one in the future. With this allocation scheme you will have limited freedom to change the netmask later with minimal hardship (renumbering). - Kurt
