When to Use DNS Propagation Checker
After DNS Changes: When you update DNS records, use this tool to monitor propagation progress and confirm when changes have reached all major resolvers.
Domain Migration: When moving to a new hosting provider or changing nameservers, track propagation to know when traffic will reach the new destination.
Troubleshooting: If some users can access your site but others can't, check if DNS values differ across resolvers and identify caching issues.
Email Configuration: When setting up MX records or SPF/DKIM TXT records, verify they've propagated before expecting email delivery to work correctly.
Frequently Asked Questions
DNS propagation is the time it takes for DNS changes to be updated across all DNS servers worldwide. When you update DNS records, different DNS resolvers cache the old values for varying periods based on TTL (Time To Live) settings.
