I have a question about connecting to the game. I'm starting renovations to my house in a few days. The contractor said it would take about two months. In the meantime, I'm moving to another house. There's no internet there right now. I'm going to set up an internet connection there and play the game from there in the next two months. After the renovations are finished, I'll have a new internet connection there. Is there anything I need to do? Since I'm going to connect from a different IP address than the one I've connected to so far?
No, you can play and vote from any network But if there are multiple players from the same household, you would need to submit a whitelist https://royals.ms/forum/threads/how-to-register-for-the-voting-whitelist.15374/
I usually play from my desktop in my house, but I received a new laptop, and will play from my girlfriends house. so I will play from other ip/macadress. is it ok? or i will banned?
As Dave said, you can play and vote from any network, no need for a separate IP. You will need to submit a whitelist request whether or not you have a separate IP if you're both playing from the same household. If you're just moving location/IP that's fine and not against rules.
