Dean-
You should have no problem with this. A 5 bit subnet mask for a class C
network would be 255.255.255.248. This will yield 32 network address with 6
hosts per address (will some one check my math :) ) Tablized this would
look like:
Network Host Broadcast
~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~
254.254.254.0 254.254.254.1 - 6 254.254.254.7
254.254.254.8 254.254.254.9 - 14 254.254.254.15
254.254.254.16 254.254.254.17 - 22 254.254.254.23
.... You get the picture.
This subnet mask (255.255.255.248) looks like this:
11111111.11111111.11111111.11111000
Where 29 bits are used for the network and 3 bits are used for the host.
Good luck,
