Looking for a bulk IP to ASN tool

  Use Team Cymru's services. For your query, I'd use their WHOIS service as it allows a bulk search with no coding (text file input/output).

  Link: Team Cymru WHOIS IP to ASN

  Relevant excerpt:

  1) Create a file with a list of IPs, one per line. Add the word begin at the top of the file and the word end at the bottom.

  Example of list01:

  `begin

  68.22.187.5
  207.229.165.18
  ...
  198.6.1.65
  end`

  Remember: you can add comments and other flags per the table above if you'd like.

  `begin

  verbose
  68.22.187.5 2005-06-30 05:05:05 GMT
  207.229.165.18 2005-06-30 05:05:05 GMT
  ...
  198.6.1.65 2005-06-30 05:05:05 GMT
  end`

  2) Run the list through GNU netcat (NOT the venerable nc).

  $ netcat whois.cymru.com 43 < list01 | sort -n > list02

  The file list02 will be sorted by origin AS, and should appear as:

  `Bulk mode; one IP per line. [2005-06-30 15:37:07 GMT]

  701 | 198.6.1.65 | UU UUNET Technologies, Inc.
  6079 | 207.229.165.18 | RCN RCN Corporation
  23028 | 68.22.187.5 | SAUNET SAUNET`

  EDIT: I see you wanted to use Maxmind, but their data can easily be outdated (as it's updated monthly). Where as Team Cymru updates their database every 4 hours (from 50+ BGP peers).

  The paid version is updated weekly (With Updates: $50 for the first month and $12 for each month thereafter), where as the free version is updated the first Tuesday of each month.
