1) pick the size of the subnet (4,8,16,32,64,128) You will lose to IP
address from each subnet (high and low) so a 4 is really 2 usable IP's.
2) netmask = 256 - <subnet size>
Example
255.255.255.256-4 = 255.255.255.252 = 2 bit/4 IP 2 usable subnet
255.255.255.256-32 = 255.255.255.224 = 5 bit/32 IP 30 usable subnet
You should route a .224 subnet to the PM2e-30's
Now you may actually be able to compete with us ;)
