CloudFlare has introduced "126.96.36.199 for families". This provides additional DNS servers as follows
Malware Blocking Only
Primary DNS: 188.8.131.52
Secondary DNS: 184.108.40.206
Malware and Adult Content
Primary DNS: 220.127.116.11
Secondary DNS: 18.104.22.168
These seem like useful features for families. They also offer secure DNS, DNS over TLS and DNS over HTTPS.
I currently use ISP DNS servers (2degrees in my case), to make sure I use ISP caches. If you switch to one of the CloudFlare DNS servers is it still true that you miss out on using the ISP caches and get lower performance for things like Netflix, or is there some system in place to mitigate that?
