Frequently Asked Questions
What is a DNS server?
A DNS (Domain Name System) server translates human-readable domain names (like google.com) into IP addresses (like 142.250.80.46) that computers use to communicate. It's often called the phone book of the internet.
Why does my DNS server matter?
Your DNS server affects browsing speed (faster DNS = quicker page loads), privacy (your DNS provider can see every domain you visit), security (some DNS providers block malicious sites), and censorship (some ISPs use DNS to block websites).
What are the best public DNS servers?
Popular options include Cloudflare (1.1.1.1) — fast and privacy-focused, Google (8.8.8.8) — reliable and widely used, Quad9 (9.9.9.9) — blocks malicious domains, and OpenDNS (208.67.222.222) — offers content filtering options.
How do I change my DNS server?
You can change DNS at the router level (affects all devices) or per-device. On most systems, go to Network Settings → DNS and enter the preferred addresses. Many browsers also support DNS-over-HTTPS (DoH) in their settings, which encrypts DNS queries.
Why am I seeing my ISP's DNS instead of the one I configured?
Some ISPs intercept DNS traffic and redirect it to their own servers (called DNS hijacking). Using DNS-over-HTTPS (DoH) or DNS-over-TLS (DoT) encrypts your DNS queries and prevents this interception.
