@majuss, thanks for your contribution!
Please resolve the comments above, and I will merge your PR.

Please don't merge just yet I need to optimise the subnet detection. Also default net 24 is maybe not helpful. 32 is in my opinion the "normal" one.

@majuss got it, I will wait for your message.

@majuss, we were working on the release today. I remember about your request)
I will fix that part as soon as possible. And your feature will be in the Gateway release v.3.8.1.

@samson0v I rewrote the find_values function to list only unique values and it works with unhashable data.
