(2019)"]]>It's important to remember, at least for corporate environments, that EDNS Client Subnet is important when working with services such as Exchange Online where the local resolver is what determines your EXO Front Door. If you're using a service like 1.1.1.1, you may be routed to an incorrect Front Door causing increased latency (primarily with search and archive mailboxes which aren't cached).

Quad9 does have a service which provides EDNS Client Subnet support, should you want to leverage it.
