Even with IPv6 you still might have stateful firewalls allowing only for outbound connection at both ends (e.g. a CPE a.k.a. “WiFi router”) and to establish communication you’d need to punch a hole in those firewalls.

That sounds very Usanian. In the meantime transportation in around me is done on foot, bicycle, bus, tram, metro, train and cars. There are good use cases for each method including the car. If you really want to use an automotive analogy, then sure, LLMs can be like cars. I've seen cities made for cars instead of humans, and they are a horrible place to live.

Signed, a person who totally gets good results from coding with LLMs. Sometimes, maybe even often.

It should always be at 0, because GitHub is unreachable over IPv6, which in 2025 should be considered an incident.

I did traffic shaping per user for a few hundred users on 1GHz Pentium III on Linux. It can be done just fine.

Was filtering done with pf, ipfw or some custom firewall?
