How to change the BlueROV2 companion computer subdomain?

I’ve attached the BlueROV2 to my LAN and I can connect to the companion computer fine, and it has internet connection. However, I cannot get QGroundControl to recognize the Pixhawk. I’m guessing this is due to my modified subdomain of 192.168.8.– I notice that many of the param files in the Raspberry Pi’s home directory has the default 192.168.2. subdomain for many things.

So… What all do I need to change in order to use my new subdomain?

For anyone else looking… I replaced all those references with that of my own subdomain. Everything worked. However, if there’s a cleaner solution, I’d love to hear it.
