Sounds like an issue with dhcpcd vs. your ISP, nothing kernel related.
Please provide more information about your IPv6 setup and maybe dhcpcd
debug logs.

As someone who does this for a living (works in bug databases), I wish
Martin would ask his questions in the pr.
From irc, I am collecting "netstat -rn" from before and after the
failure. I am also waiting for Roy to provide input on what to provide
from dhcpcd.

I had the same problem for a long while, but it got fixed on HEAD.
I would try first the HEAD kernel, and then the HEAD dhcpcd separately.

No it does not.
However, dhcpcd-7.0.0-rc2 on a NetBSD-8.99.1 kernel produces output I
would expect.
