DNS Propagation Checker

After you change a DNS record, such as pointing a domain at a new host, resolvers around the world keep serving the old answer until their cached copy expires (its TTL). This checker asks 20 public resolvers in the US, Europe, Asia and South America, plus the domain's own authoritative nameservers, at the same moment, and shows which ones already return the new value.

How to use DNS Propagation Checker

1. Enter the domain or host name, such as example.com or www.example.com.
2. Choose the record type: A for websites, MX for email, TXT for verification and SPF, and so on.
3. Click Check and compare each resolver's answer with the authoritative one.
4. If some resolvers still show the old value, wait for the TTL shown and check again.

When it comes in handy

• Moving a website or email to a new provider.
• Checking that a verification TXT record is visible before clicking "verify".
• Troubleshooting a site that works for some people but not others.

Frequently asked questions

How long does propagation take?

As long as the old record's TTL, often 5 minutes to 4 hours, and up to 48 hours for nameserver changes. Lower the TTL a day before a planned change to make it faster.

Why do resolvers show different IP addresses even after propagation?

Sites behind CDNs and some hosts (including Cloudflare and Hostinger) give different IPs in different places on purpose. If every answer belongs to your provider, the change has propagated.

Are the countries exact?

Large providers like Google and Cloudflare answer from the location nearest our server, so the country is where the provider is based rather than a guaranteed viewpoint.
