I guess this means carrier-grade NAT works well enough; given this, I can imagine ISPs just don't see enough upside to IPv6 to spend on it.
- WorldMaker 8y agoNot necessarily? It could also just mean that there are a lot of people not complaining enough, or simply without any alternatives and consigned to their fate. It would also be interesting to know how much of their traffic winds up on IPv6 tunnels like Teredo anyway to NAT break. Windows by default tries to avoid the worst NATs by using Teredo IPv6 tunneling, and has since Vista. It's certainly possible that IPv6 traffic already accounts for why users aren't complaining about how much CGNAT breaks IPv4.

Sad but true, but in the ISP's mind, this is exactly "good enough". Google's IPv6 traffic stats show Teredo traffic is negligible in 2018. https://www.google.com/intl/en/ipv6/statistics.html https://www.google.com/intl/en/ipv6/statistics.html
