AS30424
by Teun Vink 01 Feb '13

Hi all, While examining some routing table entries one of my coworkers stubled upon a number of prefixes which is are somewhat strange (or maybe even suspicious). The ASN originating these prefixes is AS30424, which is part of a block of ASN's assigned to ARIN. However, there's no entry in the ARIN database (or peeringdb, radb, etc) for AS30424. This ASN originates a number of IPv4 and IPv6 prefixes (64.186.208.0/20, 66.246.201.0/24, 66.246.202.0/24, 66.246.203.0/24, 66.246.204.0/24, 68.68.48.0/20, 98.143.176.0/20 and 2001:450:202a::/48). The IPv6 prefix (no entries in any routing database I checked) is part of 2001:450::/32, which is assigned to Level3 (AS3549), there's no route originating from AS3549 for the /32 or /48 though. The only transit for AS30424 (both IPv4 and IPv6) seems to be Cogent (AS174). The IPv4 prefixes all have entries in the ARIN database which indicate that they may be used from multiple ASNs: OriginAS: AS30424, AS36241, AS33065 The other two ASNs are registerd in the ARIN database to Megatechie. I'm mostly curious if I'm looking at an administrative error or if there's something really wrong with AS30424. Anyone have any insights? Best regards, Teun
