You aren't doing anything wrong but we need more information to figure
this out.

I believe firefox uses "happy eyeballs" which means trying v4 and v6 at
the same time and using whichever works first.

In a shell, do

ping6 nycdn.netbsd.org
ping nycdn.netbsd.org

and then traceroute6/traceroute to the same name.

You might also see if you have a global v6 address, how you got that,
what the default route is.


I would expect that sysupgrade would at least try v6 and then v4 if v6
fails.
