Yes... Should have been 2001:550:3ee3:f329:02a3:2aff:fe23:1f69.
Not sure how the extra 1 got in there.

I'm making no assertion about cogent whatsoever. Since I don't know =
whether those
addresses I chose at random within the ARIN region happen to be =
delegated or not, I
have no ability to determine whether they should be registered as =
delegated or not.
I said this in the above paragraph you quoted.
I was attempting to demonstrate the potential problem, not point to an =
extant example
as I do not have an extant example handy, though I suspect such do =
actually exist.
