Check whether a DNS change has spread, by asking six public resolvers (Google, Cloudflare, Quad9, OpenDNS, Verisign, AdGuard).
WeVivid's server asks six public DNS resolvers (Google, Cloudflare, Quad9, OpenDNS, Verisign and AdGuard) and shows what each returns. Resolvers keep old answers until their cache (TTL) expires, so changes can take minutes to hours. We don't store the domains you check.
About dns propagation checker
After you change a DNS record, it takes time to reach resolvers around the world. The checker asks several public resolvers to see whether they have the new value.
Why it takes time
Resolvers cache answers for the record's TTL. Until that time passes, some users still see the old value.
Speeding up changes
Lower the TTL (for example to 300 seconds) a day before a planned change.
Raise it again afterwards.
Test with several resolvers rather than just one.
A worked example
You change an A record and check it. Four of six resolvers already show the new address, and two still show the old one. That means the change is partly spread. Wait and check again after the old record's TTL has passed.
Why results differ
Each resolver caches the old value until its TTL runs out.
Your own router and browser add their own caches.
Flushing your local DNS cache only helps your own computer.

Your privacy on this tool
This check needs a server, so here is exactly what happens to what you type.
✓The domain, URL or IP address you enter is sent to our server over an encrypted connection.
✓Our server contacts the public website, DNS or WHOIS data on your behalf and returns the result to you.
✓We use it only to produce that result. We do not save the domains or URLs you check in a database or build profiles from them.
✓Like any web server, our hosting provider may keep standard technical logs, such as IP address, time and requested address, for security and reliability for a limited period.
✓No files are involved. Please do not enter passwords, private links or other secrets.
✓No account, email address or sign-up is needed, and nothing is watermarked.
✓If you accept analytics, we count page views and tool use. We never collect the contents of your files or text.
