FREE TOOL · NO SIGN-UP

See your DNS the way the world sees it.

We ask three independent public resolvers — Google, Cloudflare and Alibaba Cloud — at the same moment, and show you where they agree and where they don't.

How it works

Straight from the source.

Every result comes live from a recognised public source — named under your results, so you can check our work.

  1. 1
    Three resolvers, one momentWe query Google Public DNS, Cloudflare 1.1.1.1 and Alibaba Cloud DNS in parallel over encrypted DNS-over-HTTPS.
  2. 2
    Every record that mattersWebsite, mail, name server, verification and certificate-authority records — plus SPF and DMARC.
  3. 3
    Disagreements flaggedWhere answers differ, we show you — the usual sign of a change still spreading.

Private by design

No accounts, no cookies, no tracking. NuuMa doesn't store what you check. To run the tests, the address you enter goes directly from your browser to the public services named above. The only thing kept is a small daily counter in your own browser that keeps these tools free for everyone.

Questions, answered plainly

How long does DNS take to update?

Changes spread as cached answers expire. Each record's TTL (time to live) says how long resolvers may cache it — anything from a few minutes to a day or more.

Why include Alibaba Cloud?

Adding a major Asia-based public resolver to two global ones gives you a view of your domain beyond US-headquartered networks.

What does DNSSEC mean here?

DNSSEC signs your DNS answers so they can't be forged in transit. When a validating resolver confirms the signatures, we show your domain as signed and validated.
