NetList

NetList is a small networking and security auditing script I wrote in Ruby. Given a search term, it will query the ARIN database for an organization and all of its related networks. This can assist a pen tester in finding out which networks are owned by the target, and noting them for a later scan and audit.

Example Output

$ ruby netlist.rb facebook
