For years I've used Google's public DNS service. It's famous IP address is 18.104.22.168. It's a resolves addresses faster that my internet provider.
Unfortunately, by default, DNS is usually slow and insecure. Your ISP, and anyone else listening in on the Internet, can see every site you visit and every app you use — even if their content is encrypted. Creepily, some DNS providers sell data about your Internet activity or use it target you with ads. We think that’s gross. If you do too, now there’s an alternative: 22.214.171.124
