DNS Checker
Has it spread yet?
Just changed nameservers or DNS records? See what the world's three biggest public resolvers answer right now — side by side — with a plain verdict on whether your change has fully propagated.
Resolvers queried live from your browser: Cloudflare 1.1.1.1, Google 8.8.8.8 and Quad9 9.9.9.9. If they all agree, the world sees the same thing.

About the DNS Checker
Beyond's DNS Checker shows you what the internet actually sees when it looks up your domain — right now, not what your registrar's dashboard claims. It asks three of the world's biggest public resolvers (Cloudflare 1.1.1.1, Google 8.8.8.8 and Quad9 9.9.9.9) the same question at the same time and puts their answers side by side, then translates the result into a plain verdict: fully propagated, still spreading, disagreeing, or missing.
It is the tool you want in the anxious hours after changing nameservers, moving a website, connecting a domain to a new host, or setting up business email. Instead of guessing and refreshing for a day, you can watch the new records land resolver by resolver. Each resolver is given a strict 8-second window, so a slow network can never hang the whole check.
How it works
- Enter your domain. Type the domain name — with or without https://, the tool tidies it up.
- Choose the record type. Pick A, AAAA, CNAME, MX, NS or TXT depending on what you changed.
- Tap Check DNS. All three resolvers are queried live from your browser and answer one by one.
- Read the verdict. Agreement across all three means the world sees the new record. Disagreement means propagation is still under way — check again later.
Why Beyond
- Three independent global resolvers, queried simultaneously.
- A plain-language verdict — no DNS expertise needed to understand the result.
- TTL values shown for every answer, so you know how long caches may hold on.
Frequently asked questions
What is DNS propagation?+
When you change a DNS record or your nameservers, thousands of resolvers around the world must each drop their cached copy and fetch the new one. Until they all have, some visitors see the old answer and some see the new one — that spreading period is propagation.
How long does DNS propagation take?+
Often minutes to a few hours. The worst case quoted is 24–48 hours, driven by the record's TTL (time-to-live): a resolver may keep the old answer until its TTL expires. If all three resolvers here agree on the new value, you are done.
What do A, MX, NS and TXT records mean?+
A points a domain at a server's IPv4 address (AAAA is IPv6). NS names the nameservers in charge of the domain. MX routes email. TXT holds text proofs — used for domain verification and email security (SPF/DKIM/DMARC). CNAME points one name at another name.
Why do the resolvers disagree?+
Caching. Each resolver refreshes on its own schedule, so during a change one may still hold the old answer while another already has the new one. Disagreement during the first hours after a change is normal.
Is this DNS checker free?+
Yes — free, no sign-up. Queries go straight from your browser to the public resolvers.
Why does the checker show my old record after I changed it?+
Resolvers cache answers for the length of the record's TTL. Until each cache expires, that resolver keeps serving the old value. Lowering the TTL a day before a planned change makes future moves faster.
Can I check a subdomain, like mail.mydomain.com?+
Yes — enter the full subdomain. Record lookups work the same way for subdomains as for root domains.
