A linux and mac version of this shell script to show you who you are connected to on the internet To keep the output simple I have tried to show just the organisation name that you might recognise.
Download the appropriate file for your OS ( Mac or Linux )
For Mac OSX:
a) chmod +x macosx.waict.sh && ./macosx.waict.sh
or
b) bash ./macosx.waict.sh
For Linux:
a) chmod +x linux.waict.sh && ./linux.waict.sh
or
b) bash ./linux.waict.sh
As long as you as connected to things on the internet, it should print out a list of IP's and their owners. Here is an example from my mac:
➜ WAICT git:(master) ✗ chmod +x macosx.waict.sh && ./macosx.waict.sh
