by Lydia Leong | August 31, 2011 | Comments Off on The Global Internet Speedup Initiative
The rather prosaically-named, if accurately and precisely named, IETF draft specification, “Client Subnet in DNS Requests” (“edns-client-subnet”), has gotten some breathless marketing spin as the Global Internet Speedup Inititative.
I blogged about this about a year and a half ago: “Google’s DNS protocol extension and CDNs“. See that post for a deeper analysis. (I also previously blogged about the problem with using DNS as the CDN vantage point.)
My opinion on this hasn’t changed. In the intervening time, various DNS service providers and CDN providers have contributed to the draft, and the end result seems to be pretty reasonable. The extension solves a common problem for the CDNs — returning appropriately close CDN servers to an end-user who is using a DNS resolver that’s not close to his own location (common for users on some ISP networks, along with those who use resolvers from OpenDNS, Neustar, etc., and potentially for some users in enterprise networks).
But I am impressed with the amount of hype that the vendors involved have managed to generate about a fiddly little technical detail that ordinary users have probably never thought about and shouldn’t ever really need to think about.
