Get someones ip address from name and email

Question

I want to know if it's possible to get someones' IP address if I have their name, email and ID.

Answer 1

No, it's not. That person could access your application from anywhere, and if all you have are his name, email and user ID, that's not going to tell you anything about what machine he's coming from.

Answer 2

What do you mean by his id? An email address and a name are not sufficient to retrieve an IP.
