NextDNS - the resolver as a configurable filter
Public resolver where the blocklists, logging and retention are the user's settings.
NextDNS operates a public resolver whose filtering is configurable per profile: which blocklists apply, what is logged, and for how long. It sits at the opposite end of the same axis as Quad9 - one resolver decides policy for you, the other hands you the controls.
The comparison is the useful part of having both on this timeline. A default-blocking resolver protects a network whose operator will never configure anything, which is most networks; a configurable one serves an operator who has an opinion and wants it applied consistently across every device.
Both share the property that makes resolver-level filtering attractive and uncomfortable at once: it applies to everything on the network without installing anything, and it works by having somebody else see every name you look up.
