A lot of US ISPs have no ipv6 configured.
(There are roughly 3,000 different ISPs in the US.)
But I’m not sure the cost of running these shims for forever is worth what they’re holding back.
The only question remaining in my mind is if the world is ready for ipv6 … but maybe it’s better if we at least set a date.

A bigger drawback is that you end up in a bad neighborhood. 20 years ago, most traffic from tunnelbroker users were people excited about ipv6 with isps that didn't care about it. In 2026, nobody is excited about ipv6 anymore and tunnelbroker traffic is mostly abuse or trying to circumvent georestrictions... Expect to fill out so many captchas if you set it up.
cogent gonna cogent. i think you're still probably good for the most part.

For my network I wanted something I had some chance of remembering so I consulted a dictionary and ended up with fdbe:aded:cafe:babe::/64.
I do have a ULA network I chose for myself. But when I'm not at home I would like to be able to reach things I self host (e.g. my Navidrome server), and I need routable IPs for that. My /60 from Comcast is stable but not guaranteed to be static, and it would be nice to have a truly static allocation so I won't run into the need to redo my DNS records if Comcast ever changes my prefix. I know I could script something to do that, but static is a bit nicer.
An HE.net tunnel has advantages, but they’re also quite bandwidth–constrained. If you need anything more than ~1MB/s then you should build something yourself instead.
