DNS checker FAQs

DNS propagation is the time it takes for updated records to spread across DNS servers worldwide. It typically takes a few minutes to a few hours, but can take up to 24–48 hours depending on TTL values and how often resolvers refresh their caches. Lowering your TTL before a migration speeds the process up.
Enter your domain in the DNS checker above and select the record type you changed. The tool queries DNS servers around the world and shows which ones return the new records and which still serve the old ones — so you can confirm a migration is complete before switching traffic.
The checker supports 8 record types: A, AAAA, CNAME, MX, TXT, NS, SOA, and SRV. That covers website hosting, mail routing, domain verification (TXT), nameserver delegation, and service discovery in a single tool.
DNS resolvers cache records for the duration of the TTL. A server that fetched your record an hour ago keeps serving it until the TTL expires. Differences during propagation are normal; persistent mismatches after 48 hours usually mean a misconfigured nameserver.
Yes — check your MX records to confirm they point to the right mail server, and verify SPF, DKIM, and DMARC via TXT lookups. Missing or incorrect mail records are the most common cause of messages landing in spam or bouncing.
No. The DNS checker is completely free with no account required, and every query runs live against real DNS servers — so you always see current records, not cached results. Run as many lookups as you need, and bookmark it for your next migration.
