Purge Results per Resolver
No Resolvers Found
No resolver entries match the active filter criteria.
DNS resolvers cache records so the internet doesn't have to look up the same domain thousands of times a second. Useful, until you've just changed a record and every resolver on the planet is still confidently serving the old one.
Moreover, Clear DNS Cache tool actively requests a fresh lookup from more than 25 major public resolvers, including Google (8.8.8.8), Cloudflare (1.1.1.1), Quad9, OpenDNS and several regional networks, forcing them to drop the stale entry and pull the current one.
Instantly flush your domain's DNS cache across all major public DNS resolvers globally.
Easily purge cache for A, AAAA, CNAME, MX, TXT, NS, SOA, and SRV records with one click.
Queries all providers asynchronously in parallel, ensuring immediate status updates without waiting.
When to run this
- Immediately after changing nameservers
- Right after updating an A record to point at a new server
- After modifying MX records for a new email provider
- Any time a DNS change feels like it's taking longer than expected to show up
Setting expectations
Full global propagation can still take anywhere up to 24 to 48 hours in the worst case, that's a function of TTL settings outside anyone's direct control. Flushing the major public resolvers just means a large share of everyday traffic sees your update far sooner than it otherwise would. Want to see exactly where it stands first? Run a DNS Propagation Check before and after to confirm the flush actually worked.
FAQS
What does clearing the DNS cache do?
Clearing the DNS cache forces public DNS resolvers (like Google, Cloudflare, and Quad9) to drop their stale cached records and fetch the latest DNS information directly from your domain's authoritative nameservers.
When should I use this tool?
You should use this tool immediately after changing your domain's nameservers, updating IP addresses (A records), or modifying email (MX) records to speed up global propagation.
Which DNS resolvers are supported?
The tool queries over 25 major resolvers globally, including Google (8.8.8.8), Cloudflare (1.1.1.1), OpenDNS, Quad9, AliDNS, NextDNS, and many other independent and regional networks.
How long does it take for changes to appear?
Normally, DNS propagation can take up to 24-48 hours. By using this tool to actively flush the cache of major public resolvers, many users will see your changes instantly.
