Now, this is interesting; AS 1221 is not in ARIN or anywhere.

No match for "1221".

Iny my view of the world, 1221 is wholly transited by Exodus:

*>i210.9.34.0       209.67.40.13                  100      0 3967 1221 4736 i

They have lots of AS's behind them, including 9443, 4730, 4736, etc.

ARIN: What about people who use AS's that aren't assigned to them?

Community: Should one filter these announcements?

Exodus: Don't you care?
