DNS Propagation Checker

DNS propagation is the delay while DNS resolvers around the world refresh their cached copies of your records after you make a change. Your authoritative nameserver updates instantly, but other resolvers keep serving the old value until their cached TTL expires. DNS Dingo queries multiple global resolvers at once so you can see exactly which locations have picked up the new record.

It depends almost entirely on your record's TTL. With a low TTL (300 seconds) most resolvers update within 5 to 15 minutes; with a standard 3600-second TTL it is usually 1 to 4 hours, and full global propagation can take up to 24 to 48 hours because some ISPs cache longer than the TTL requests. Run your domain through DNS Dingo's free checker to watch propagation in real time.

Yes. DNS Dingo is free forever with no signup and no credit card, and you get a generous daily allowance of lookups across A, AAAA, MX, CNAME, TXT, and NS records. Paid Pro ($9/mo) and Business ($29/mo) plans add higher limits, extra record types, API access, bulk checks, and lookup history for teams that need them.

Enter your domain in the checker at the top of this page, pick a record type (or All Records), and click Check DNS. DNS Dingo queries multiple global DNS resolvers simultaneously and shows the propagation percentage, per-server results, and an interactive world map. When every server returns your new value, propagation is complete.

Usually it is caching, not a mistake: resolvers hold the old record until its TTL expires, and some ISPs override low TTLs and cache for up to 24 hours. Other causes are editing the wrong record, a high TTL set before the change, or registrar delays. Lower your TTL before planned changes and use DNS Dingo to confirm which resolvers are still serving stale data.

On Windows, open Command Prompt as administrator and run ipconfig /flushdns. On macOS, run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. On Linux with systemd, run sudo systemd-resolve --flush-caches, and remember to also clear your browser's DNS cache. Flushing only clears your local cache, so use DNS Dingo to see the global picture.

Select MX in the record-type dropdown, enter your domain, and click Check DNS to see every mail-exchange record and its priority across global resolvers. MX changes follow the same TTL-based propagation as other records, typically completing within a few hours. This is the fastest way to confirm a mail provider migration (Google Workspace, Microsoft 365, and similar) has gone live everywhere.

DNS Dingo checks A (IPv4), AAAA (IPv6), MX (mail), CNAME (aliases), TXT (SPF, DKIM, DMARC and verification), and NS (nameserver) records for free. Pro and Business plans add SOA, SRV, and CAA records. Choose All Records to pull everything for a domain in a single lookup.

DNS Dingo checks propagation across multiple global resolvers with an interactive world map, response-time data, and a clean modern interface with no ads or signup. It runs lookups directly over DNS-over-HTTPS in your browser, so results are fast and private. For related checks, pair it with IP Impala for IP geolocation and HTTP Tiger for HTTP status and header testing.

Yes. DNS Dingo runs queries over encrypted DNS-over-HTTPS to trusted public resolvers, and the free checker requires no account, so we do not ask for or store your personal data. Lookup history is only kept if you choose a paid plan that includes it.

The free plan covers A, AAAA, MX, CNAME, TXT, and NS lookups with a daily allowance and no signup, which is enough for most developers. Pro ($9/mo) raises the daily limit, unlocks SOA/SRV/CAA records, and adds API access and 30-day lookup history. Business ($29/mo) adds unlimited lookups, bulk multi-domain checks, and CSV/JSON export for migrations and agencies.
