List of DNS Servers that do use ECS!!

[#1]

I am finding very outdated articles that are sponsored crap from various companies about DNS Servers that support ECS. I use cloudflare and while I like it I heard ECS isn't natively supported by CloudFlare's DNS nor Google's. And a search on Google shows a bunch of sponsored posts for DNS hosting with ECS which isn't what I want. I am trying to find a public DNS server that supports ECS and see if the claims behind ECS are true for websites with CDNs placed in front of their sites.

Thank you for joining the Infoblox community forums. Infoblox does not currently provide a public DNS service but if you are looking to use Infoblox for your own DNS solution, Infoblox appliances do support ECS (EDNS-Client-Subnet, RFC-7871).
