Hi,

While I was debugging DNS, I happened to notice, the Anonymized EDNS Client Subnet feature doesn't work with Akamai's CDN. I found information from Akamai, they enable ECS for Google DNS and OpenDNS https://community.akamai.com/customers/s/article/Akamai-to-Enable-ECS-for-OpenDNS-GoogleDNS-on-IPA-SXL-Network

I suggest NextDNS team to collaborate with Akamai to enable ECS, optimize DNS results when sending ECS.

* With domain www.apple.com & e1.o.lencr.org: The IP addresses are all on Akamai server at ISP FPT, while I am using ISP Viettel.

NextDNS have the infrastructure and the contacts to make this a really easy change. Worth doing imo.

  I also hope NextDNS' ECS will be approved by Akamai and respond to CDN server IP addresses on the same carrier (if available).
