How long does DNS propagation take?

DNS propagation typically takes between a few minutes and 48 hours, depending on the TTL (Time to Live) value of your previous DNS record. Records with a low TTL (300 seconds / 5 minutes) propagate quickly. Records with a high TTL (86400 = 24 hours) may take up to that duration to update on all global resolvers.

How do I check if my DNS has propagated worldwide?

Enter your domain into the DNS lookup tool and select the record type (A, AAAA, MX, etc.). The tool queries your domain from 50+ nodes across different countries simultaneously, showing which locations see the new record value and which are still returning the old cached value.

What DNS record types can I check?

The tool supports over 20 record types: A, AAAA, CNAME, MX, NS, TXT, PTR, SOA, SPF, SRV, CAA, DNSKEY, EDNS, AXFR, MAILB, MAILA, MD, MF, MB, MG, MR, NULL, WKS, and MINFO. Select the record type from the dropdown before running the check.

What is the difference between an A record and an AAAA record?

An A record maps a domain to an IPv4 address (e.g. 93.184.216.34). An AAAA record maps a domain to an IPv6 address (e.g. 2606:2800:220:1:248:1893:25c8:1946). Most modern servers support both. The A/AAAA combined check tests both simultaneously to show whether IPv6 has propagated alongside IPv4.
