DNS Propagation Checker

Check whether your DNS changes are visible across multiple major public resolvers. Great for A, AAAA, CNAME, MX, TXT, NS, and SOA records.

Matched / Visible
Resolvers returning the expected or current record clearly.
Propagation %
Quick signal for how widely the record is visible.
Consensus Value
Most common answer across resolvers.
Query
Current domain + record type checked.

Resolver Result TTL Latency
Ready
Enter a domain, choose a record type, and run the check.

How to read this

Strong green results mean the resolver returned a record and it matches the expected value or the current consensus. Mixed results usually mean propagation is still in progress.

Tip

For planned DNS changes, lower TTL ahead of time when possible. After changes, compare A, CNAME, MX, TXT, or NS records depending on what you updated.

FAQ

What is DNS propagation?

DNS propagation is the time it takes for updated DNS records to become visible across different DNS resolvers around the internet.

What record types can I check here?

You can check A, AAAA, CNAME, MX, TXT, NS, and SOA records with this DNS propagation checker.

Why do some resolvers show different results?

Resolvers may return different answers because cached DNS records expire at different times, propagation is still in progress, or your DNS update has not reached every resolver yet.

How do I know if my DNS changes have propagated?

If multiple resolvers return the same expected value and the propagation percentage is high, your DNS change is likely visible across most of the internet.
