I was curious as to how this sort of thing works with twitch.

I live in a house with 4 other people, there are 3 computers in the house. If 3 of us are watching the same stream from the 3 computers how does twitch count the views since they are all from the same IP?

Also how does this work if 1 of those people is streaming and the other 2 are watching the person who is streaming?

I hope that all makes sense. I just want to make sure if I'm streaming and the other people in the house are watching my stream I'm not going to get in crap or banned because some of my viewers are coming from the same IP even if it's only 2-4 people (sometimes the others watch on their phone).
