    What is DNS?

    ~15s
    DNS (Domain Name System) is the internet's phone book. When you type "google.com," DNS looks up the actual numeric address (like 142.250.80.46) that computers use to find the website. Without DNS, you'd need to memorize numbers.

    How it works

    ~15s
    You type a URL. Your device asks a DNS server "what's the address for google.com?" The DNS server responds with the IP address. Your browser connects to that address. This happens in milliseconds.

    Why it matters for speed

    ~15s
    A slow DNS server means every website takes longer to load. Switching to a faster DNS can make browsing noticeably snappier. It's one of the easiest performance upgrades you can make.

    Why it matters for privacy

    ~15s
    Your ISP's DNS server sees every website you visit. Switching to a privacy-focused DNS (Cloudflare 1.1.1.1 or Google 8.8.8.8) means your ISP can't easily log your browsing activity.

    How to change your DNS

    ~15s
    On your router (affects all devices): log into router settings, find DNS settings, enter 1.1.1.1 and 1.0.0.1 (Cloudflare). Per device: Windows (Network settings > DNS), Mac (System Settings > Network > DNS).

    Recommended DNS servers

    ~15s
    Cloudflare (1.1.1.1): fastest, strong privacy. Google (8.8.8.8): very fast, reliable. Quad9 (9.9.9.9): blocks known malicious sites. OpenDNS (208.67.222.222): family safety filtering available.
