Thanks you so much. i have tried this coding. While loading am getting an error message that "This application requires a minimum of 1 supported sockets.". i have comment block the form loading. (SocketsInitialize) If i type anything in the text box, it i

ISP IP? or your IP Address?

You can use is use M$ winsock control; Try it,

put winsock on form, then add this code in form load event;

   Debug.Print Winsock1.LocalIP

then check your immediate window, you will see your IP Address (Same address that you can see on http://www.whatismyip.net/)

Thanks for your reply. As per this coding it is showing the local machine ip only. i want to know my internet service provider IP Address.

Thank you so much. i have tried this coding. While loading am getting an error message that "This application requires a minimum of 1 supported sockets.". i have comment block the form loading. (SocketsInitialize) If i type anything in the text box, it is working fine. for example if i type www.google.com then its apprearing the IP. If i leave it blank it is showing my Local IP(DHCP). I am using STATIC IP Broadband connection. i want to know the Internet Service Provider IP Address. (www.whatismyipaddress.com).
