I believe he's onto something there...routable addresses would be 172.16.254.81 thru 172.16.254.94 on 28 bits...and there's that pesky rule about having your gateway on the same subnet as the node. :)

That's correct. Write down 80, 1 and 240 in binary. With a /28 mask,
your IP address and your gateway are in different subnets.
