DNS (Domain Name System)

The system that translates website names (like google.com) into IP addresses. Your DNS provider affects how fast websites begin loading and can improve security and privacy.

What It Means

Every time you type a URL, your device queries a DNS server to look up the IP address. Most people use their ISP's default DNS, which can be slow and may log browsing activity. Switching to a faster DNS like Cloudflare (1.1.1.1), Google (8.8.8.8), or Quad9 (9.9.9.9) can reduce initial page load times by 20-50 ms. DNS does not affect download speed or speed test results, but it affects perceived browsing speed because every new website requires a DNS lookup before data transfer begins.
