Yet you keep doing the same about judging people. That's hypocrisy at
work.

On a slow machine, about a millisecond, yes. That matters in high
performance computing, where professionals do the administration. It
does absolutely not matter on a personal workstation that spends 99 %
of its CPU cycles waiting for keystrokes anyway.

Of course there are stupid ISPs who that send IPv6 on absurd detours.
Those need to be put out of business.

Can you provide evidence that such a delay will never happen without
broken routes? Or is it up to the implementation that asks for the
address?

While I don't recall details, I think I've seen and read about this
behaviour too. Only for one case with my computers do I remember it
being a stale route or assignment. For those back in the past I don't
recall much.

I was planning not to mention this, given I don't have much to recall,
but if you're going to insist on that aggressive approach, judging
people, taking a chance at bullying if someone dares to use ifconfig,
and at the same time asserting the problem doesn't exist, I don't think
I can afford not to comment.
