"Cloudflare's 1.1.1.1 DNS will respond very fast, but the big sites you access, the whole reason for resolving DNS, will be SLOWER ∵ no edns-client-subnet support, so no geolocation of results." - https://twitter.com/philpennock/status/980561009961299968 https://twitter.com/philpennock/status/980561009961299968
- kentonv 9y agoedns-client-subnet leads to a surprising number of privacy concerns. See: https://00f.net/2013/08/07/edns-client-subnet/ https://00f.net/2013/08/07/edns-client-subnet/ I find the cache timing issue particularly worrying. Cloudflare runs from 151 (and growing rapidly) locations worldwide. Without edns-client-subnet, the upstream DNS server will probably respond according to the geolocation of the Cloudflare location you're talking to -- which is probably pretty close to you, and therefore will probably produce a good outcome for you, while largely avoiding the privacy concerns.
