DNS Propagation Checker
See what 10 public resolvers, run by operators around the world, return for a domain, live.
Pins show where each operator is based. Queries go from our server over DNS over HTTPS, and anycast services answer from their node nearest to it.

Frequently asked questions
What is DNS propagation?
When you change a DNS record, resolvers around the world do not all learn about it at once. Each one keeps its cached copy of the old record until the record's TTL (time to live) runs out. The period while some resolvers show the old value and others show the new one is called DNS propagation.
How long does DNS propagation take?
Usually from a few minutes to a few hours. The record's TTL sets the upper bound for most resolvers, so a 3600-second TTL means up to an hour. Changes to nameservers can take longer, sometimes up to 48 hours.
Why do some resolvers show different results?
Either they still hold the old record because its TTL has not expired, or the domain uses geo-based DNS, as many CDNs do, and returns different IP addresses depending on where the query comes from. Both are normal. This tool marks any resolver whose answer differs from the majority as inconsistent.
How can I make DNS changes propagate faster?
Lower the TTL on the record well before you make the change, for example to 300 seconds, then change the record after the old, longer TTL has expired. You can raise the TTL again afterwards.
Where are the queries sent from?
From our server, to each resolver's public DNS over HTTPS address. Each answer comes from that resolver's cache, so the tool shows whether resolvers have picked up a change. Large services such as Google and Cloudflare are anycast: the node nearest to our server answers, so the map shows where each operator is based, not where the answer was measured.
Which DNS record types can I check?
A and AAAA (IPv4 and IPv6 addresses), MX (mail servers), NS (nameservers), TXT (SPF, verification and other text records), CNAME (aliases) and SOA (zone authority information).
