ok heres the situation, i would like to setup a ip scheme so i know where a pc is located on the network i would like to have ip addresses of 10.x.x.x the netmask is the part i am having trouble with. i was wanting to run 10.x.x.x/13 so i could have 64 subnets (i was only going to use 50 of them, 1 for each state)if i do that i only leaves 3 bits for a location number which only has 8 posibilites, some states have as many as 16 locations, any suggestion how to do this?
