I'm seeing some IPv6 on starlink (and had to troubleshoot another person on
starlink that had a corporate access problem that was resovled by disabling
IPv6)

I thought Starlink was not supporting IPv6, because of this:

Nate gave me the opportunity to test a bit of ipv6 access on one of
his dishys today. I am going to give p2p a shot, also, and he
conveniently has bbr2 installed. It is of course difficult to discern
the difference between transport behaviors and their underlying
connectivity - for example the BBR2 result attached has a baseline
(idle!) latency jump of over 40ms which is hard to explain.
Despite these plots saying downloads, they were essentially uploads
from his box over the internet.
The summary of the data I have so far on this direction is:
Cubic, looks like cubic, usually, but not always. BBR rarely looks like BBR.

Vint just asked me a difficult question over here about the
performance of the ISL links for my upcoming AMA next week
https://twitter.com/mtaht/status/1639361656106156032
And to date, we really don't know. We do know it is up!? but...
has anyone managed to measure p2p ipv6 performance starlink to
starlink over an ISL link as yet? Do we know anyone at the poles? In
general I always look for flent and irtt data, but I'd settle for a,
oh, call it 5-10 minute long packet capture of single iperf flow,
running over tcp cubic (bbr would be great too).... one test in each
direction.
(in fact that would be great from any starlink terminal to any of my
servers around the world)
I have some data from a couple of you (thx ulrich in particular!), but
I have not sat down to take it apart as I have been far, far too busy
with libreqos and a bunch of nice, small, competent ISPs deploying
that, to worry about fixing a billionaire's network all that much....
but I've set aside next week to answer AMAs about everything from all
and sundry, so if you got data, please share?
