DNS to Block Ads: How to Stop Ads on Any Device Fast

Using a DNS to block ads works by routing your internet traffic through servers that filter and block ad-related domains before they load on your device.

What Is DNS and How Does It Block Ads?

DNS (Domain Name System) acts like the internet’s phonebook. When you use a special DNS that blocks ads, it prevents your device from connecting to known ad servers.

So instead of ads loading, they simply don’t appear at all.

• AdGuard DNS
  • Primary: 94.140.14.14
