How can I monitor the IP change for a DynDNS

Votes:

Ich have to monitor a change of the IP with DynDNS. Is there a sensor for this Problem? The Traceroute sensor is not practicable, because the hops are the same after a change.

Hi Lukas,

Ah, you confused me with the title of your question.

I'm sure however that the Traceroute sensor can help you out here, as in your example 'google.de' will be the last entry in the hop list.

So the route will change if the IP for 'google.de' changes!

Please make sure to select 'Set sensor to warning' or 'Set sensor to down' in the sensor settings page.

Also note that the sensor wil only stay in this state for one sensor run only, as with the next run the route will not have changed compared to the prevous run.

Hi Lukas,

You might want to have alook at Custom Sensor DNSDynamic.

It monitors changes of your public IP and updates your DynDNS setting accordingly.
