Users often find Google’s solution to resolve addresses faster than their ISP; this is simply because they will be connecting to another network – Google DNS in their device settings too.
As such, the giant search engine collaborated with Akamai to advance the speed of accessing location-based Akamai hosted content. The joint venture will allow Google Public DNS to propagate client location information to Akamai name servers thereby improving the accuracy of approximately 30 percent of the location-sensitive DNS responses returned by Google Public DNS.
What this means is that all client requests made to Akamai hosted content can be directed to closer servers with lower latency and greater data transfer throughout.
Yunhong Gu, Tech Lead for Google Public DNS said, “Overall, google Public DNS resolvers serve 400 billion responses per day and more than 50% of them are location-sensitive.”
He added, “A group of DNS and content providers, including Google, proposed an approach to allow resolvers to forward the client’s subject to CDN nameservers in an extension field in the DNS request. The subnet is a portion of the client’s IP address, truncated to preserve privacy. The approach is officially named edns-client-subnet or ECS. The Google Akamai collaboration marks a significant milestone in our ongoing efforts to ensure DNS contributes to keeping the Internet fast. We encourage more CDNs to join us by supporting the ECS option.”
