AS3745 is not a duplicate ASN assignment either. Like AS35868 the entry at whois.ripe.net is a user created object in the RIPE routing registry, not an assignment by RIPE NCC.
How can you tell one from the other? Is the lack of an org: attribute reliable?
The info is in the as-block object which whois.ripe.net returns in addition to the aut-num object when you do a default query for an AS number. For example for as43210 you get this: as-block: AS43008 - AS44031 descr: RIPE NCC ASN block remarks: These AS Numbers are further assigned to network remarks: operators in the RIPE NCC service region. AS remarks: assignment policy is documented in: remarks: <http://www.ripe.net/ripe/docs/asn-assignment.html> remarks: RIPE NCC members can request AS Numbers using the remarks: form available in the LIR Portal or at: remarks: <http://www.ripe.net/ripe/docs/asnrequestform.html> org: ORG-NCC1-RIPE admin-c: CREW-RIPE tech-c: RD132-RIPE mnt-by: RIPE-DBM-MNT mnt-lower: RIPE-NCC-HM-MNT source: RIPE # Filtered [...] Only AS numbers which are covered by "RIPE NCC ASN blocks" have been assigned by RIPE NCC or transferred to RIPE NCC (like AS1707). -- Rene
