Check whether a DNS change has propagated: query public resolvers worldwide, see them on a map and refresh on a timer.
Enter a domain to check DNS propagation across global resolvers
DNS propagation is the time it takes for changes to a domain's DNS records to spread across the global network of resolvers. When you update an A record, MX record, or any other DNS entry, the new value doesn't appear everywhere instantly - each resolver caches the old answer until its TTL (Time To Live) expires.
This tool queries 17 public resolvers in parallel using DNS-over-HTTPS (DoH). If all resolvers return the same answer, your change has propagated. If some return the old value and others the new one, the change is still spreading - usually completes within minutes for low TTL records, up to 48 hours for records with high TTLs. To speed up propagation, lower your TTL to 60 seconds before making a change.
Resolvers checked: Google (8.8.8.8), Cloudflare (1.1.1.1), NextDNS and ControlD (global); CIRA and CleanBrowsing (Americas); dns.sb, Mullvad, LibreDNS, Digitale Gesellschaft, and BlahDNS Germany and Finland (Europe); Tiarap, DNSPod, and BlahDNS Japan and Singapore (Asia); and Shecan (Middle East). Results are cached for 30 seconds to prevent rate limiting.
