Not sure what to make of #Quad9 (IBM'S new DNS service).
The privacy policy seems better than Google/OpenDNS. No storage/transfer of IP data and they even disable EDNS0 (on their main IP).
There is no support for DNSCrypt or DNSCurve, but they do support DNS-over-TLS. Which makes some sense, considering they are targeting IOT devices that are unlikely to support DNSCrypt or have the HW to do so.
Free DNS with active threat blocking could be big security win for everyone.
If you're interested in #Quad9, the IP is 9.9.9.9
