Correct. I'm not sure how accurate this really is, but: http://www.cdnplanet.com/blog/which-cdns-support-edns-client-subnet/ Basically, it helps pass the client IP upstream so the CDN can make a better guess to which cluster to direct you to, instead of the query-source IP of the recursive they are talking to. We've seen poor CDN performance as a result of them only being granular to a /24 scope, as well as folks using the 'wrong' dns servers and being sent to CDN nodes a few networks or continents away. - Jared _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations dns-jobs mailing list https://lists.dns-oarc.net/mailman/listinfo/dns-jobs
