Yes - Here it is :AS 3010 SPRINT-MRN-BLOCK | 1 prefixes | 1 prefixes & 1 ASN supported | 4094 Addresses | 14 hops | as path 174 3491 18734 28509 3001 3002 3003 3004 3005 3006 3007 3008 3009 3010
here is the only address block :*> 201.160.16.0/20 38.101.161.116 4001 0 174 3491 18734 28509 3001 3002 3003 3004 3005 3006 3007 3008 3009 3010 i
I assume that this is some odd internal Sprint thing - maybe a lab in Mexico as it is going through 28509 ?
28509 MX-TCSC23-LACNIC [RUM] {62270 - cuernavaca - MO, MX} TV Cable S.A. de C.V.
None of the other 3001-3009 appear directly. Could this be some new form of AS path prepending ? I really don't know. Regards Marshall
