Well isn't that interesting. My BGP peer is configured with remote AS = 4436. Looking glass says the AS path is 3257 > 40926. So they're re-writing AS#'s or something. Meh, I don't care.

Just an observation:-
Because we had Ip transit from both networks Nlayer and Tinet ..we had much more noticeable visibility into their network. changes. In some locations (e.g. Atlanta), as part of the network collapse, they were using both ASN's on the same router. We were able to see this when both of our BGP Sessions were collapsed on to the same Router...

It is possible that they have done similar @ 350 Cemack.
If you look at bgp.he.net, you will see that AS4436 is becoming a placeholder / internal ASN for them.

    We're peered at 350 E Cermak. Maybe they said screw it, 350 will
    be AS4436. Like buildings that have their own zip code.

        (although not sure why not).

        I got an email many months ago saying that's what they're
        doing. We're peered with 4436. So I asked, when are we
        coordinated to be moved to 3257? They said... you're not.
        Umm.. Ok. So I don't know WTF their plan is. Maybe they're
        going to stick with the 4436 as regional and 3257 as global plan.

            FYI, GTT is collapsing their network (nlayer AS4436 ) into
