One thing to keep in mind. I ran into this with Cox's Level 3 entries. The Origin field in Level 3 database is often incorrect, but the entries are required for their acl's. So, even though a network may be advertised by a Cox customer, the ASN listed in L3 is Cox's ASN (which isn't unexpected since Cox is the one who entered the data).

So AS11908 may be transiting those networks into Level3.
