**Dynamic DNS update via IP Notify message**

The camera´s built in Dynamic DNS client is only able to send updates for its own IP address unfortunately not for the public IP address of the router that is providing its gateway to the internet.

Most routers have a built in DynDNS client but if that is not the case it may be possible to update the DynDNS service by using IP Notify messages.

The following example is based on using the No-IP service. You can check with your Dynamic DNS service for the API commands needed to perform a similar update.

In the case where the DynDNS provider does not receive the IP from the client, it uses the IP of the origin of the HTTP request. In some cases ISPs do not assign an actual public IP address to the customers router (3G/4G particularly). In such cases this approach will not work.
