retrieve routing informations efficiently via dns queries
asdig is a simple tool for retrieving ASN (autonomous system number) match from IPv4/IPv6 published by services like Rezopole GoASMap (http://github.com/rezopole/goasmap) or Cymru. For a given IPv4 or IPv6 it would display current BGP anouncements received at the BGP-infrastructure of the queried IP-to-AS reference server, or Internet Exchange Point (IXP) subnets from PeeringDB, or reserved subnets from Internet Assigned Numbers Authority (IANA). For a given AS number it would display a digest of the registered informations from Regional Internet Registries (RIR).
