Today, I have tested Netlist Script. According to the author
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.
The results are very helpful for pentesters at the Information Gathering phase. This tool if expanded to include all five Regional Internet registries (RIR) I will be very happy :):
- Help when evaluating pricing and timing required for a client to do a pentest job
- Save pentester time
- help scope the target
