DNS checker: has your change reached everyone?

Enter your domain. We read all of its records and ask the same questions of your own nameserver and three large public DNS resolvers, so you can see whether the change you made has reached everyone.

  • No sign-up, full result
  • A, AAAA, CNAME, MX, NS, TXT, CAA, SOA
  • Propagation across 4 resolvers

We only make public DNS queries. We don't connect to your website or your mail server.

What it is

What DNS and propagation are

DNS translates your domain into addresses computers understand: which server holds the website (A record), who receives the email (MX), who runs the DNS itself (NS), plus other settings (TXT, CAA).

When you change a record, for example because you're moving the website to a new server, not everyone sees the change at once. Internet providers' DNS resolvers keep the old answer for as long as the TTL says. That's called propagation, and this check shows you how far it has got.

How it works

  1. 1

    Enter the domain

    For example example.com. You can also paste a full address or an email.

  2. 2

    We read the records

    A, AAAA, www, MX, NS, TXT, CAA and SOA, as a visitor sees them.

  3. 3

    We ask four servers

    Your domain's own nameserver, which has the newest answer, plus Cloudflare, Google and Quad9.

  4. 4

    We tell you what it means

    Who runs the DNS, where the website points, whether www is missing and whether your change is visible everywhere.

When you need it

When to check your DNS

  • After a hosting move

    See whether every large resolver already points to the new server before you close the old account.

  • When the website won't open

    A missing record, a forgotten www or nameservers that don't answer show up here at a glance.

  • Before new email or SSL

    MX, TXT and CAA records decide whether your new email and your SSL certificate will work.

FAQ

About your domain's DNS

How long does a DNS change take to show everywhere?

As long as the TTL of the record you changed, usually from a few minutes to a few hours. Changing nameservers takes longer, up to 48 hours, because the servers of the domain ending (.com, .gr) cache it too. The check shows whether your nameserver and the large public resolvers already give the same answer.

I moved servers but still see the old website. Why?

Your computer, your browser and your internet provider keep the old answer until the TTL runs out. Try your phone on mobile data, or a private window. If every resolver here already shows the new IP address, the change was made correctly and you only need to wait a little.

What are nameservers and where do I change them?

They are the servers that hold your domain's records. You set them at the company you bought the domain from (the registrar). If you change them, for example to move to Cloudflare, every record must exist on the new nameservers first, or the website and email stop working.

What's the difference between an A record and a CNAME?

An A record points straight to an IP address. A CNAME says "ask this other name instead" and is often used for www or for services such as Shopify and Wix. On the bare domain, without www, you normally use an A record only.

Do I need a CAA record?

It isn't required, and most domains don't have one. It lists which certificate authorities may issue SSL for your domain, so nobody else can get a certificate in your name. If you add one, include the authority you already use.

Do you check SPF, DKIM and DMARC too?

SPF shows up here among the TXT records. All three, though, are checked in detail, with a grade and explanations, in the separate email check tool.Check SPF, DKIM and DMARC

Want us to handle the move?
