DNS Propagation Checker
Check if your DNS changes have spread worldwide. Queries 15+ global locations to see what each resolver returns.
What is DNS Propagation?
When you change DNS records (add SPF, switch hosting, set up email), the changes don't take effect everywhere at once. DNS resolvers around the world have caches — they hold onto old results for minutes to hours. Propagation is the time it takes for every resolver to get your new records.
