I know this post is not related to the subject.. but i didnt find anywhere else to post
i wanted to know how do big companies..like yahoo or anything else.
Can track pcs
im NOT saying going to ip-adresses.com...
but real professional tracking...
Also if i have an ISP my ip location will be their location where i am.
on top of that they do not give you a stable ip.. it changes all the time.
Another thing is the rumors that if someone tries to hack into any big company system.. they will track him under 30 seconds..
SO how do they do it ???
