ELi5 Netflix said they will charge more if someone outside of your household uses it. How can they tell?

Question

If it’s based on IP address, wouldn’t me veiwing on mobile be affected? If I travel and log in through a hotel wifi, do I have to pay extra every month?

Answer 1

I use my parents’ Netflix more than they do, since they’re 150 miles away on metered internet and I have fiber. We’ve never had an issue, but I’m willing to guess it’s because they use it so rarely.
