Their product range is utlised by quite a few big-players in conjunction with CDNs such as Akamai etc... I suspect their pricing will turn out to be quite expensive, but if you need specific 'dynamic' DNS resolution, based on latency, client IP geo-location etc... then they are the commercial solution I would consider. I am sure that many other companies have similar product offerings (so as not to make this a specific plug for a commercial product on a non-commercial mailing list). ___ 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

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 ___ 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

Is bind support conditionally resolution?
I am designing a big deploy system, which will implement via DNS. The demond is misc, one of them is conditionally resolve, which means that if one CDN node near unavailable, or latency increased significantly, no matter why, I want bind to give another second best result, which located in distant places. Is bind support this natively? Or I have to write external program? If bind doesn't support, is there any other DNS impletions I can try? ___ 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
