Great suggestion Kevin. Passing 0.0.0.1 as gateway_ip_template (or whatever you call it) is essentially passing an address index, so when you OR 0.0.0.1 with the CIDR you get your gateway set as the first usable IP in the subnet. The intent of the user is to allocate the first usable IP address in the subnet to the gateway. The wildcard notation for gateway IP is really a more convoluted way of expressing this intent. Something like address_index is a little more explicit in my mind. I think Kevin is on to something.

That isn't a valid IP address, AFAIK. It isn't a valid *IP* address without the network part. However, it can be referred to as the "host address on the network" or the host part of the IP address.
