How does Edns client subnet work?
When an authoritative name server receives a DNS query, it takes advantage of ECS DNS extension to resolve the hostname to a CDN which is geolocationally near to the client IP’s subnet, hence the client makes further requests to a nearby CDN, thereby reducing latency. …
What is extended client subnet?
What is the EDNS Client Subnet (ECS)? ECS is a DNS extension proposed in 2011 by a group of DNS and CDN operators. It allows recursive resolvers, if they are willing, to forward details about the origin network from which a query is coming when talking to other name servers.
Does Google DNS support ECS?

Does Cloudflare DNS use ECS?

What is a DNS client?
– Recursive query. A DNS client requests a DNS server to give a response. – Iterative query. This query happens when a DNS resolver can’t find the answer in its database, so the query is forwarded to the Root Nameserver. – Non-recursive query. This query is the fastest since the DNS resolver finds the DNS record in its cache and returns it to the user.
