Common Questions About Public DNS
This page answers common questions people have about Public DNS in clear, plain-English language.
Straight answers about Public DNS
What is public DNS in simple terms? It is a DNS resolver service that anyone can use instead of only a private or ISP-provided resolver.
Is public DNS the same as web hosting? No. Public DNS helps resolve names, while hosting delivers the website or application.
What people usually misunderstand
A public DNS resolver receives DNS lookup requests from devices and returns the answers needed to reach domains and services.
The device asks the resolver to translate a domain name into the correct network destination, and the resolver performs that lookup process.
Public DNS matters because resolver speed, reliability, privacy posture, and filtering behavior can affect a user's internet experience.
People often use public DNS when they want a faster resolver, more predictable performance, or a different provider than the default one supplied by a local network.
