Finding a reliable, fast and secure DNS server can often feel like searching for a needle in a haystack. However, a well-chosen DNS server can significantly boost your internet speed and enhance security, especially when it’s free and public. Here’s a guide to 18 of the best DNS servers you can consider in 2025.

Configuring DNS on Your Devices
Changing your DNS settings is a straightforward process, and here’s how you can do it on major devices:
Windows

MacOS
- Open System Preferences → Network.
- Select your connection → Advanced.

Using a public DNS server can significantly boost your online experience in terms of speed and security. However, pairing your DNS with a robust VPN elevates your privacy to new heights, ensuring that your online activities remain confidential. By selecting one of these top free DNS providers for 2025, you’re taking a significant step toward a safer, faster internet. But remember; always prioritizing privacy and security is essential in navigating the digital world securely.
