You pretty much have a rigid set of choices. Either 2 nets of 64 usable,
or 6 nets of 30 usuable. There are plenty beyond that, but I think the 30 is
your case. Here is what the mappings would look like:
Note however, the 1st and last from each subnet is a network and broadcast
address (therefore non-usable).
Netmask = 11100000
224
First subnet = 00100000 - 00111111
32 63
Second sunbet = 01000000 - 01011111
64 95
Third subnet = 01100000 - 01111111
96 127
Fourth Subnet = 10000000 - 10011111
128 159
Fifth subnet = 10100000 - 10111111
160 - 191
Sixth subnet = 11000000 - 11011111
192 - 223
