Can someone track my ip address nd ultimately my phone number thru social networking sites?

[Aubrey]

When i use facebook twitter or tumblr can anyone see my ip address nd get to my phone number. How do i prevent it from happening. I am using a mobile

Prevent it. Dont give them the phone number in the first place and use an email that has been set up for FB not your regular one. Only an expert could trace your IP let alone get account details which is something quite different.
