From the site that the DDNS address should be directing traffic too, open a web browser. The go to Google and type ‘What is my IP address’. This should show a results similar to below.


Alternatively visit and the sites current IP address will be displayed across the middle of the screen:



You will need to make a note of the IP address shown in the results, which ever method you use.

Next open a command prompt window.


In the command prompt type:

ping <full ddns address> then press enter.



This will display a result similar to the image below.


Next you will need to compare the IP address that the google or method provided with the 'Reply from' line shown in the command window.
