Strike me as curious, but this seems as if Connexion by Boeing is handing off a /24 from ASN to ASN as a certain plane moves over certain geographic areas. Or is there some other explanation?

They presented at NANOG saying they would be re-announcing a /24 per plane as it crosses the ocean. I can't recall if the originating (or transit) ASNs were going to change, but it doesn't seem wholly unreasonable. IMHO, of course. -- TTFN, patrick -- "Fergie", a.k.a.
