I believe this is typically done at higher level. This higher level often supports serving different responses based on geographical location, latency etc.This information is derived from the IP prefix using EDNS and by using anycast IP addresses etc. I don't think any of this should be at the rr level. I do agree that the higher level configuration language would be neat to standardize but it's out of scope of this draft. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
