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.
