It's impossible to have a full 36-bit subnet mask, so that must be some kind of mistake.
Typically you would connect your EN/SC box to a switch or router. If you were to go to your router's config page, and the IP you used to get there was "192.168.1.1" then that would be your gateway. For the machine's IP address you could use anything between 192.168.1.2 and 192.168.1.254, as long as there are no duplications anywhere else on the network. (this is presuming you're using a 255.255.255.0 subnet mask, most consumer rotuers do by default.) For a DNS I would just use 4.2.2.1, or you can use whatever your ISP recommends.
