DNS propagation check
Have your domain's DNS records reached DNS servers in different parts of the world? After a name server, IP or MX change, you can see here which servers have updated the record.
If you enter an IP address, its reverse DNS (PTR) record is looked up.
Why does DNS propagation take time?
When you change a DNS record, the new value first appears on the domain's authoritative name servers. Servers run by internet service providers and public DNS services, however, keep the old answer in their cache until the record's TTL expires.
Authoritative servers
These are the servers listed in your domain's NS records. They hold the correct value of the record, and the tool compares the other servers against this answer.
Public DNS servers
Resolvers used by visitors, such as Türk Telekom, Google, Cloudflare and Quad9. If you see an old answer, their cache has not yet been refreshed.
TTL
Specifies in seconds how long the record is kept in cache. Lowering the TTL to 300 seconds before a migration speeds up the switchover.
A record changes usually propagate within a few minutes to a few hours. For a name server (NS) change, this can take up to 24–48 hours depending on the extension.
Which record should I check?
| Type | What it does | When to check it |
|---|---|---|
| A | Points the domain to an IPv4 address. | When you move your site to new hosting or a new server |
| AAAA | Points the domain to an IPv6 address. | If your server uses IPv6 |
| CNAME | Links one name to another (e.g. www → main domain). | When connecting a subdomain, CDN or online store platform |
| MX | Specifies which server receives email sent to your domain. | When you move business email to another service |
| NS | Shows which name servers manage the domain's DNS. | When you point the domain to another company or to Cloudflare |
| TXT | SPF, DKIM, DMARC and verification records for services such as Google and Microsoft. | If email lands in spam or a service asks for domain verification |
| CAA | Restricts which certificate authorities can issue SSL for your domain. | If an SSL certificate cannot be issued |
| SOA | The zone's primary server, serial number and timing settings. | To see whether a change has reached the authoritative servers (serial number) |
| SRV | Specifies which server and port a service (e.g. _sip._tls, Minecraft) runs on. | When setting up a game server, VoIP or Microsoft 365 |
| PTR | Maps an IP address back to a name (reverse DNS). | If you send email from your own server |
Frequently asked questions about DNS propagation
Some servers show a different IP. Is something wrong?
The old site still opens on my own computer. What should I do?
ipconfig /flushdns command in the command prompt and restart your browser. If the problem persists, try restarting your modem or waiting a few hours.The authoritative servers row shows "No response".
