Change DNS Settings: Windows, Mac, iOS, Android

Jump to your platform: Windows 10 & 11 · macOS · Linux · iOS · Android · Router. Already changed them? Verify the change took effect.

Your device asks a DNS server to turn every domain name you type into an IP address. Which server it asks is a setting you control, and changing it can make browsing measurably faster, block a category of hijacking attacks, and stop your ISP from seeing every site you look up.

Below are the exact steps for Windows 10 and 11, macOS, Linux, iOS, Android and your router, followed by how to check the change actually took effect. It takes about two minutes on any of them.

Why Change Your DNS Server?

Before diving into the instructions, here are some reasons to change your DNS server:

  • Faster internet browsing - Some DNS servers respond faster than your ISP's default servers

  • Enhanced security - DNS servers with built-in malware and phishing protection

  • Better privacy - DNS servers that don't log your browsing activity

  • Content filtering - Block adult content or ads at the DNS level

  3. Look for DNS settings under sections like:

    • Internet Settings

    • WAN Settings

    • Network Settings

    • Advanced Settings

  4. Enter your preferred DNS server addresses in the Primary DNS and Secondary DNS fields

  5. Save the settings and reboot your router if required

Common Router Brands

Verifying Your DNS Settings

After changing your DNS settings, verify they're working correctly:

The quickest check is to check propagation across global resolvers and confirm the answers come from the servers you set.

  1. Flush your DNS cache:

    • Windows: ipconfig /flushdns

    • macOS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

    • Linux: sudo systemd-resolve --flush-caches

  2. Test your DNS resolution using online tools or command line:

  3. Browse a few websites to ensure everything is working correctly

Troubleshooting

If you experience issues after changing DNS settings:

If the steps below do not help, it is worth understanding how DNS resolution actually works before changing anything else.

  • Double-check that you entered the DNS addresses correctly

  • Restart your device or router to ensure changes take effect

  • Try a different DNS server if one isn't working

  • Revert to automatic DNS settings if problems persist

  • Check if your ISP or network blocks custom DNS servers

Conclusion

Changing your DNS server settings is a simple way to potentially improve your internet experience. Whether you're looking for faster speeds, better security, or enhanced privacy, the public DNS servers listed in this guide offer various benefits. Remember to test your connection after making changes and keep a note of your original settings in case you need to revert.

One thing this guide does not cover

Everything above changes which DNS server your device asks. That is a resolver setting, and it only affects you.

If you also own a domain, there is a second set of DNS records: the ones that answer for your domain when anyone else looks it up. Those live at your registrar or DNS host, and nothing tells you when they change. A wrong MX record silently reroutes your email. An expired certificate or a lapsed registration takes the domain down. In practice people find out from a customer.

Run a free scan of a domain you own: it reads every record from every authoritative nameserver, checks your certificates, and grades the domain against 47 security checks. No signup, no card.

If you want the same checks to keep running, DNS Spy re-resolves every monitored domain at least every ten minutes and alerts you when a record changes. See how monitoring works.
