You mean ENDS0 Client Subnet (ECS) turned on inside your DNS Resolver architecture. If you are an ISP/Operator and want to get the most out your CDN ‘partnerships,’ then you should really be running ECS. But, if you do turn it on, know that there are scaling issues.

If ECS is new, let me know and I’ll send a pointer.
