Why does DNS matter?
The Domain Name System (DNS) protocol is an important part of the web's infrastructure, serving as the Internet's phone book: every time you visit a website, your computer performs a DNS lookup. Complex pages often require multiple DNS lookups before they start loading, so your computer may be performing hundreds of lookups a day.
Try it out
- Configure your network settings to use the IP addresses 220.127.116.11 and 18.104.22.168 as your DNS servers.
- Or, read our configuration instructions (IPv6 addresses supported too).
If you decide to try Google Public DNS, your client programs will perform all DNS lookups using Google Public DNS.
In addition to traditional DNS over UDP or TCP, we also provide DNS-over-HTTPS API.
Looking for Cloud DNS?
Public DNS is only a name resolver. If you are looking for a high-volume, programmable, authoritative name server using Google's infrastructure, try Google's Cloud DNS.
