Angry IP Scanner
Angry IP scanner is fast and friendly network scanner for Windows, Linux, and Mac. It is very extensible, allowing it to be used for very wide range of purposes, with the primary goal of being useful to network administrators.
Well put (the above paragraph was taken from the description found on its project page) but for me Angry IP Scanner it a fast and dirty ip scanner.
I bet you all remember your first ‘auditing’ tool, I do. You may guessed it, it is Angry IP Scanner, and it goes almost six years back… Anyway don’t want to bore you with old stories, but you can take it for granted that it is the fastest ip scanner out there.
