Dynamic DNS
Note - If you are only using the module(s) on a local network and not via the internet then you can safely ignore this section
If you have configured a module with port forwarding for internet based control then you need to have a static IP address; one which never changes. Domestic connections do not usually have a static IP address and often have one that changes each time a connection is established. If this is the case with your connection you will need to use a re-direction service. Once correctly configured you will be able to access your ip switch from any internet connection by entering your hostname into the browser bar.
