Fix common DNS server problems by flushing your DNS cache, switching servers, and restarting your router. Step-by-step tips.

Cloudflare's 1.1.1.1 remains a strong choice for privacy and speed, though the best DNS server depends on your needs.

Google's 8.8.8.8 remains fast and reliable in 2026, but Cloudflare and other providers are just as competitive. Test it yourself.

Learn how to change your DNS settings on a router or device, and how to test multiple providers to find the fastest one.

DNS is required for normal browsing and should not be turned off. Here's what people usually mean when they ask this.

The four DNS server types are recursive resolver, root server, TLD server, and authoritative server. Here's how they work together.

Without DNS, devices can't translate domain names to IP addresses, so websites become unreachable by name. Direct IP access still works.

The internet technically works without DNS if you know exact IP addresses, but DNS makes it usable by translating domain names.

Using DNS lets you browse with domain names instead of memorizing IP addresses. Here's a simple look at how the lookup works.

8.8.8.8 is Google's public DNS resolver, translating domain names into IP addresses for any device configured to use it.

DNS itself is a standard internet function, but risks like spoofing exist. DNSSEC and trusted providers help protect your lookups.

DNS spoofing redirects users to fake, malicious sites by corrupting DNS resolution. Learn how it works and how it relates to DNS leaks.
