If the phone has some sort of data-plan on it, subpoena the mobile phone company to reveal all the IP's associated with that phone number.
But, the big question is, what would you do with the IP addresses?
Tempting one to do bodily harm to themselves or others is a crime. Call FCC ... Can be a felony.
I have some questions:
1) what "number" are you talking about? Their phone number? You will never get an IP address from that
2) If you have their IP, how do you propose to 'find out who it is'?
3) Even if you do find out who it is, then what are you going to do?
Wouldn't it make more sense to get a firewall for Grandma, a good antivirus (or, maybe a Mac), and teach her safe computing?
Someone cannot see your facebook profile "on your IP address" .. they can very easily and simply just go to Facebook.com to see it. If your profile is private, having your IP address will not help them in any way.
Nobody can see your messages unless they have access to the Facebook system/servers or have your Facebook password.
If someone has your IP address about all they might be able to see is the type of device you are using.
some IP scanner programs will get the device model information - or you can do it manually from your comptuer but I dont know the commands.
oh really? having someones IP address could get me LOADS of stuff including Facebook username&password
1)using telnet to hack it
2)going to the destination of their Google Chrome(IE,Mozilla.etc)
3)saved passwords - if there is nothing there then things are getting complicated***
*** If nothing is there then you would have to access their browser history
If you are REALLY REALLY REALLY REALLY unlucky and they CTRL+Shift+N or Delete their history then the most you could do is go and cry in a corner
Hope it helped - And I dont see why you are talking if you clearly have no clue about what you are talking...
I guess the key word in your sentence is "could".. I suppose you COULD get all that stuff IF your target is running some kind of old, unpatched Windows 95 or XP computer, does not have any firewall/router, has no password protection, the stored passwords you're after arent encrypted, AND if that computer even has a Telnet server daemon on it.
yah.. I guess you COULD do all of that with an IP.. But in reality, usually, you CANT .. But posting that made you look really, really smart and awesome, so you've got that going for you.
