Can you see these AS links:)

[Kai Chen <kch670 () eecs northwestern edu>]

Hello folks,
As part of a research project here at Northwestern, we have found quite a
few unexpected AS-level links that do not appear in public available BGP
tables. We really need your help in validating them; for anyone who knows
links associated with any AS, if you can assist us with this please contact
us off list.

Thanks!
