Dynamic DNS

If you have configured a module with port forwarding for internet based control you need to have a static IP address, that is 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 such as the free option at www.noip.com and configure the “target” in the module to be your dynamic DNS host name.

The Dynamic DNS update client is the inbuilt software that will periodically check your external (broadband router WAN) IP address and, if it has changed, notify and update your Dynamic DNS account.
