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.
