If in windows, go to a DOS prompt and type in "ipconfig" and hit Enter.

Also try "ipconfig -all" as it gives more information about your settings.

Just to clarify a few things to everyone.

When you go to the websites that Mike just posted, you will get your ISP assigned IP address. This is your "external" IP address that connects you to the world of the internet.

When you use the IPCONFIG utility that Larry posted, you will see your "internal" IP address, the IP addresses located within your own personal home/office network.

In order to effectively troubleshoot any connectivity problems it is important to know the difference between these two types of IP addresses.

hmm whats the use of this post?

"What is my IP address?"

That says it all! If you want to find out how to get your IP address, public or private.... you can find out how to do it here.

It is for the convenience of those who DON'T know how to find this information, why you would need your IP address depends on your issue.

what happens when after u type in ipconfig and press enter. the command prompt shows, then it closes down w/o showing anything..

That's when you need to open up command prompt first before you enter the command, else if you just type the command in run then you'll get that disappearing result.

ipconfig /all
