Click here
(it will open in a new window)

Leave that window open and disconnect from the internet,wait 5 seconds and connect to internet again.
Now that you have done it :

Click here
(opens in a new window)

After you have done it go look at the first window where it says "Your ip is:" and in the second window where it says "Your ip is :"
If the ip's are identical(same) you have static ip and if they are not you have dynamic ip

example:

In the first window : Your IP:
66.249.72.136

In the second window : Your IP
66.249.72.136
you have static ip



if any of the numbers are changed you have dynamic ip
