Hello Michael, in case of both IPv4 and IPv6 connection, the query string in the update URL may contain both a "myip" and a "myipv6" key simultaneously. (for single protocol updates, "myip" may be used for either protocol) As far as i understand the ddns sources, simultaneous updates are not possible. This may be resolved on the server side in the future. A possible workaround could be to always include both addresses in the update URL, independent of the "protocol" argument of the update method.
