I figured it would change up after power outages. But recently it's been changing at least once if not more. I have a certain configuration that crashes if I'm not attached to address from before. So I need to set up the the configuration again. If I'm browsing it's not always noticeable. You might notice if you're logging onto a website that wants you to verify again. The vpn I use definitely notices and jacks up my streaming.
Just curios. If it's dynamic that answers a lot of questions
