Right.  Linux has good support for it.  But a Nokia Gateway 3 ONT
fiber modem?  Not so much as it turns out!

Oh there has been a terrible misunderstanding!  I have IPv6 to my
house Noika ONT fiber modem.  But the Nokia just seems buggy providing
it to my machines.  By machines I mean my Devuan/Debian machine or my
FreeBSD machine.  I set up an Ubuntu 24.04 as a "standard system" in
order to have a dedicated debug system.

As you can see I have IPv6 addresses.  Lots of IPv6 addresses. Several
more than I need.  Now if they were all WORKING addresses then I would
have something!

It's a similar problem on FreeBSD and my other Linux kernel machine
too.  Two different operating systems are giving basically the same
results makes me think the problem is not in them but in the Nokia.
