DNS Propagation Checker

DNS propagation is the time it takes for DNS record changes to be updated across all DNS servers worldwide. When you update a DNS record (like changing your web server IP), the change doesn't happen instantly everywhere — it spreads gradually as each DNS resolver refreshes its cache.

This tool queries multiple public DNS resolvers from different geographic locations to help you determine whether your DNS changes have propagated globally. Each resolver is queried directly via DNS-over-HTTPS (DoH), giving you accurate, real-time propagation status.

1. Enter Domain — Type the domain name you want to check (e.g., example.com). Do not include http:// or www.
2. Select Record Type — Choose the DNS record type to check: A (IPv4), AAAA (IPv6), CNAME, MX, NS, TXT, or SOA.
3. Click Check Propagation — The tool queries 8+ global DNS resolvers via DNS-over-HTTPS and displays results in real time.
4. Review Results — Each resolver shows its response time, location, and the DNS records it returned. If all resolvers return the same result, your DNS has fully propagated.
