What it does
Check DNS propagation instantly across 20+ global servers. Free, fast, and modern DNS checker tool to verify your DNS records worldwide. Also includes SSL certificate checker, WHOIS lookup, domain age checker, and HTTP header analysis — all in one clean toolkit. No signup required. Built for developers and sysadmins.
Free global DNS propagation checker. Enter any domain to instantly test DNS records (A, MX, CNAME, TXT) across 21 global servers in parallel. No ads, no signup.
DNSFly queries your DNS records from 21 servers across North America, Europe, Asia-Pacific, South America, Africa, and Oceania. You see which locations have picked up your latest change and which still serve the old answer. Just updated your A records , switched nameservers , or added MX records for email? Run a check and confirm the new values have reached resolvers worldwide before you rely on them. All 10 record types are supported: A, AAAA, MX, CNAME, NS, TXT, SOA, SRV, PTR, and CAA. Each result shows the server location, provider, response status, and resolved value. A world map plots them so you can spot a lagging region in seconds.
