Adding to cmenghi's issue, I have also recently run into issues with dyndns updating.

My internet connection has been excruciatingly unstable lately (separate issue, I hope). When my connection drops, I am invariably getting a new IP each time. Sometimes the dyndns update process is able to handle this without incident, other times, it fails with the same errors cmenghi has referenced. Verbose Sanitized logs follow:

The response payload "dnserr" is a reply from curl that it failed to resolve the hostname to send the update. What DNS servers are you using? They're apparently unreachable when it tries to do the update.

Thanks for the explanation cmb.

FWIW, I am using Google Public DNS:

8.8.8.8
8.8.4.4

Is there a retry interval option for failed updates other than the cron entry? Perhaps a flag that gets raised when the update fails and a process that checks for a failed update at a greater frequency than the default cron?
