Urgh I wish it were like that here in Australia! We have a fast, modern fiber internet connection in inner Melbourne. But my ISP still doesn't support IPv6 at all. I file a ticket about once a year, and I'm always met with more or less the same response - essentially that there's no demand for it.

I'd love to test all the internet services I host to make sure everything works over IPv6, but I can't. At least, not without using a 4to6 relay of some sort - but that adds latency to everything I do.

I just checked - apparently my ISP is "evaluating IPv6" because they're running out of IPv4 addresses and want to use CGNAT for everyone. I suppose its not the worst reason to switch to ipv6. But they've been making excuses for years. I really wish they'd get on with it.
