Is it DNS?
It's always DNS… or is it? This runs the real checks in your browser — the big resolvers, your own DNS, and whether a major provider is the one having a bad day.
Querying Cloudflare, Google and DNS.SB, testing your local DNS, and checking major-provider health…
So… is it DNS?
Three things go wrong and all feel identical — this tells them apart:
- Your local DNS is broken. The internet works, but your device/router can't turn names into addresses. (The classic "it's always DNS.") Fix: switch your DNS to 1.1.1.1 or 8.8.8.8.
- A big provider is down. If the major resolvers/clouds fail across the board, it isn't you — Cloudflare, Google or AWS is having an incident. Sit tight.
- It's not DNS at all. Names resolve everywhere and providers are up, so the problem is one specific site/app, or your own machine.
FAQ
How can I tell if it's DNS or my internet connection?
This tool separates them: if you can reach sites by IP but names don't resolve, it's DNS; if nothing is reachable at all, it's your connection.
Why do different DNS resolvers return different IP addresses for the same site?
That's normal for large sites using CDN, anycast or geo-balancing — it isn't a DNS problem. This checker tests whether resolution works, not whether the IPs match.
How do I fix it when my own DNS is the problem?
Switch your device or router DNS to a public resolver like Cloudflare (1.1.1.1) or Google (8.8.8.8), which usually clears local DNS failures.
