Get Ip Address

I am looking for a way to retrieve the local machines IP address with out getting it out of the registry.

Is there an API that I can use

Any suggestions would be greatly appreciated

Here I pulled this of somewhere on the internet, it's not mine...
1) Make a Command1 commandbutton
2) Make a Text1 textbox
3) Make a module
place this code into a module

place this code into command1_click

Text1 = GetIPAddress

Alternatively..

Stick a Winsock Control on Your Form and Read the LocalIP Property.
