To be frank, everyone should be behind CGNAT unless they need access to do port forwarding.
At the end of the day, how many compromised routers are there out there with the classic admin/admin credentials that is just accessible via the internet?
Is there any benefit to giving mobile devices IPv6 addresses anyway? CGNAT works. Customers don't care if they use IPv4 or IPv6. 99.99% of customers just want to be able to watch a video, maybe make a WhatsApp call. No one really cares about what is used as long as they can do what they want to.
It was ok today. The main issue is the heat buildup inside. Couple of days where it hits 27/28 and it stays warm inside. Really still feels like summer for the most part.
