As Matus said DNS is not a good place for such magick. Nonetheless you can use Bind with DLZ and some third-party script/program which will change database entries depending on reachability or latency. May be you should look at PowerDNS, it has something called "Dynamic resolution" and its resolver has scripting support. _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to > unsubscribe from this list > > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users > -- -- AP
