The top query is an Exodus query, as you can see Digex only sees it from
the Exodus PXs. The bottom query is AT&T's 12.0.0.0/8, which is not only
seen directly from 7018 (AT&T) but from AS1 (the Planet). That is transit.
I'd show you from BBN's route server, but it doesn't prove anything since
it is a RRC, and wouldn't show the longer as-path's anyways.
