I found that Cloudflare DNS seems to be sending EDNS Client Subnet
Although the IP received by Akamai is not my own, it is still related to my network operator.
Akamai does not receive ECS for queries made through Quad9 DNS
On my WARP Plus enabled Mac, querying through 1.1.1.1 still causes Akamai to receive an ECS associated with my real IP.
Is this normal as expected?
This is expected - this (single) Akamai debug domain has ECS enabled for cross-provider debugging, but we do not send ECS to any of their production domains (such as akamaihd.net or similar).
If our policy on ECS changes, we’ll make an announcement ahead of that so that users are fully informed.
