Best DNS Servers for Faster Internet
Your DNS (Domain Name System) server translates website names into IP addresses. A slow DNS can make your internet feel sluggish even with a fast connection.
What is DNS?
How It Works
1. You type "google.com"
2. Your device asks DNS: "What's the IP for google.com?"
3. DNS responds: "142.250.185.46"
4. Your device connects to that IP
