Should add one more filter: EDNS client subnets.

Some like cloudflare doesn’t support that in the name of privacy.

EDNS lets the dns server of the site you are visiting know from where you are connecting and can give you the closest server. 1.1.1.1 does not do that. This breaks all sorts of ISP cache and peering arrangements.

Here’s an example: My ISP’s google global cache is broken every time I use cloudflare. With google dns, opendns, isp’s own dns I get my ISP’s own ip address for the domain “googlevideo.com” which is where youtube videos load from. With cloudflare dns I get an ip address of an actual google server which may or may not be in my country. Result: my downloads from google drive/youtube/play store all are faster with a dns server with proper EDNS support.

Now imagine this on a global scale for smaller websites, your request might go to a different continent.

I understand the product decision for cloudflare and I don’t want them to change but this is something people should know about. There are numerous reports on their forums which are always locked with no activity.

I am not saying it’s a conspiracy but this doesn’t affect sites on cloudflare btw due to their global anycast routing/infra setup which I don’t know enough to explain.
