Hi ianhaynes,
great to hear that you solved the problem.
There seems to be no way in Android Nougat of setting or changing the ip address
The first thing to do is open up the Network settings. Once there, long-press the network in question and tap Modify network. Next, tap the Advanced options drop-down, tap the IP settings drop-down, and tap Static. In the new window you are able to an IP address, a gateway address, network prefix length, and two DNS servers.
