Google DNS supports both IPv4 and IPv6. You can configure your devices to use Google Public DNS with either protocol, or both.
Understanding Google Public DNS
Google Public DNS is a free, global Domain Name System (DNS) service that you can use instead of your ISP's DNS servers. This service translates domain names, like "www.google.com", into IP addresses that computers can understand.
How Google DNS Works
- When you type a web address in your browser, your computer sends a DNS request.
- If you're using Google Public DNS, your request goes to Google's DNS servers.
- Google's servers look up the IP address associated with that domain name and send it back to your computer.
- Your computer then connects to the website's server using this IP address.
Configuring Google DNS
The official documentation states that you can configure Google Public DNS addresses for either IPv4 or IPv6 connections, or both. This flexibility allows users with different network setups to utilize Google's DNS service effectively.
Google Public DNS Addresses
| Protocol | Primary DNS Server | Secondary DNS Server |
|---|---|---|
| IPv4 | 8.8.8.8 | 8.8.4.4 |
| IPv6 | 2001:4860:4860::8888 | 2001:4860:4860::8844 |
Why Use Google DNS?
- Speed: Google's DNS servers are generally very fast, which can improve your browsing speed.
- Reliability: Google operates a vast global infrastructure, making their DNS very reliable.
- Security: Google employs security measures to protect users from DNS-related attacks.
Conclusion
In summary, Google DNS supports both IPv4 and IPv6. The reference confirms this by stating that users can configure their settings for either or both types of connections.
