Check global DNS propagation for A, AAAA, CNAME, MX, TXT, NS, SOA, CAA records using worldwide nodes + map view.
The DNS Propagation Checker from Sync Soft Solution helps you verify how your DNS records resolve across multiple regions worldwide. It’s ideal after updating A records (new server IP), changing nameservers (NS), connecting a CDN, or setting up email authentication with SPF / DKIM / DMARC. You can quickly check record consistency and understand why some users see the new DNS while others still receive old cached results.
DNS (Domain Name System) converts a domain name (like www.example.com) into an IP address
(like 203.0.113.10) so browsers can connect to servers. When you visit a website, your device first checks
its local cache. If no valid cache exists, it asks a recursive resolver (DNS server) which retrieves
the answer from authoritative sources and caches it for a time called TTL (Time To Live).
DNS propagation is the common term used to describe the period when updated DNS records appear differently across the internet. DNS doesn’t “propagate” like a file transfer—results update as different resolvers refresh their caches. That’s why one location may show the new IP instantly, while another still shows the old record.
DNS changes can appear within minutes, but in some cases may take 24–72 hours (or longer). The time depends on:
The best method is to lower your TTL (for example, to 300 seconds) 24–48 hours before making major DNS changes. After the update, verify results globally using this tool. If your local device still shows old data, flush DNS cache or test using an alternate resolver.

Different DNS resolvers cache records for different durations. Some may still serve the older record until their cache expires.
If you recently changed DNS, re-check every 5–15 minutes initially, then periodically until all major regions show consistent results.
Email setups typically require correct MX records and TXT records for SPF, DKIM, and DMARC.
Yes. You can check subdomains like www.example.com or mail.example.com depending on the record type.
