Some services can also block access to phishing or infected sites, and a few offer content filtering to keep your kids away from the worst of the web.
OpenDNS
Primary, secondary DNS servers: 208.67.222.222 and 208.67.220.220
With filtering or pre-configured protection, you can safeguard your family against adult content and more. It’s the easiest way to add parental and content filtering controls to every device in your home.
Cloudflare
Cloudflare
Primary, secondary DNS servers: 1.1.1.1 and 1.0.0.1
Privacy is another major highlight. Cloudflare doesn't just promise that it won't use your browsing data to serve ads; it commits that it will never write the querying IP address (yours) to disk. Any logs that do exist will be deleted within 24 hours. And these claims aren't just reassuring words on a website. Cloudflare has retained KPMG to audit its practices annually and produce a public report to confirm the company is delivering on its promises
Google Public DNS
Primary, secondary DNS servers: 8.8.8.8 and 8.8.4.4
Quad9
