Do you plan to support IPv6 -> ASN mappings as well, at some point?

Another interesting feature related to that would be supporting special resolution of 6to4 addresses (RFC3056); looking up 2002:0102:0304:: would give you also the info on IP 1.2.3.4.

Indeed _also_, as the source ASN's can differ between the ASN's used for announcing the IPv4 and the IPv6 prefix. Fortunatly, except for currently 4 prefixes, there should not be something more specific than 2002::/16 per RFC3056.

From GRH: 2002:c2b1:d06e::/48 More specific 6to4 prefix (194.177.208.110/32) from AS5408 2002:c8a2::/33 More specific 6to4 prefix (200.162.0.0/17) from AS15180 2002:c8c6:4000::/34 More specific 6to4 prefix (200.198.64.0/18) from AS15180 2002:c8ca:7000::/36 More specific 6to4 prefix (200.202.112.0/20) from AS15180

BTW if somebody has a working contact for AS15180, don't mind to mention it, as they seem quite unresponsive... Others did respond and cleansed it up btw :) Greets, Jeroen -----BEGIN PGP SIGNATURE----- Version: Unfix PGP for Outlook Alpha 13 Int.
