Check DNS propagation worldwide and see how DNS records are resolving from different public DNS locations.
Check DNS records through multiple public DNS resolvers.
Use our free DNS Propagation Checker to see whether your domain's DNS changes are visible across different DNS resolvers. Enter a domain name, select a DNS record type, and check the latest DNS responses.
DNS propagation refers to the process of updated DNS information becoming available through DNS resolvers and networks around the internet. After changing nameservers or DNS records, different resolvers may temporarily return different results because of caching and TTL values.
This tool checks your selected DNS record through multiple public DNS resolvers and shows the returned value. This can help you determine whether a DNS change is resolving consistently.
An A record maps a domain to an IPv4 address.
An AAAA record maps a domain to an IPv6 address.
An MX record identifies the mail servers responsible for receiving email for a domain.
A CNAME record points one hostname to another hostname.
An NS record identifies the authoritative nameservers for a domain.
There is no single fixed propagation time. DNS caches, TTL values, resolver behavior, nameserver changes, and local network caching can affect when a DNS change becomes visible.
DNS information is cached by recursive resolvers according to TTL values. Because different resolvers may have different cached versions, DNS changes can appear at different times from different locations.
The tool reports the responses returned by the selected DNS resolvers at the time of the check. Results can change as DNS caches expire and resolvers obtain newer information.
Yes. You can check DNS propagation online for free without installing additional software.
DNS propagation describes how updated DNS information becomes available through different DNS resolvers and networks after a DNS change.
The time can vary depending on TTL values, caching, resolver behavior and the type of DNS change. There is no universal fixed propagation time.
Some DNS resolvers may still have the previous record cached. They can return the new value after the cached information expires and the resolver refreshes the record.
Yes. The tool can check A records and compare responses from multiple DNS resolvers.
Yes. Select MX from the record type selector to check mail-server DNS records.
Yes. Select NS to check the nameserver records returned by the selected DNS resolvers.
Different resolvers can have different cached data or may query different authoritative servers while DNS changes are being updated.
Yes. This online DNS propagation checker is free to use.
