On September 1, 2015, OpenDNS will begin providing EDNS0-client-subnet ("ECS") data in DNS requests to Akamai authoritative DNS servers for the Akamai domain supporting our Session Accelerator (SXL) and IP Session Accelerator (IPA) products (akasripcn.net).


Also, on September 2, 2015 Google DNS will make a configuration change to complete their transition to sending ECS data for akasripcn.net. However, in their case, the benefits of this change were already realized several months ago.


ECS data in a DNS request provides additional information (such as the end user's client IP) that allows Akamai to make smarter/more optimal routing decisions for centralized third-party DNS authorities (like Google DNS and OpenDNS).


At the time of this post, Akamai uses ECS data from Google DNS and OpenDNS on many of its end user-facing platforms to optimize its end user routing, and the IPA/SXL Network will be the latest Akamai platform to start leveraging this technology.


No action is required, and this change should be transparent for all end users.
