Your statement is not matching the operational realities I live in. I understand how mapping is done in my current environment. I understand how it is done in many of my peer CDNs. I also understand the tools I would need to measure better path calculations. Everything is in IP, RIPs, FIBs, AS Patch, system load, content availability, etc. Knowing that it is in Palo Alto California is not something useful. What is needed is the allocated IP block to start the mapping determination. Then every CDN does their “secret sauce” to delver the best customer experience. Geographic location is just not one of those factors. ECS delivers this now. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
