Global DNS Propagation Checker
Instantly verify DNS records across 24+ global nodes. Ensure your domains are routing perfectly worldwide.
How DNS Propagation Works
When you update a DNS record (like changing hosting providers), those changes don't happen instantly worldwide. ISPs and core internet routers cache old IP addresses to save bandwidth. Our tool queries massive root and regional servers (Google, Cloudflare, Quad9) simultaneously to show you exactly which geographic regions have received your latest data updates.
What is a 'Good' Result?
A healthy domain should see all green checkmarks returning the exact same IP Address or Record. If some servers return red crosses (NXDOMAIN) or old IP addresses, your domain is still actively propagating. Full global propagation can historically take 24-48 hours, though modern infrastructure often completes in 1-4 hours.
Record Types Explained
- A: Maps domain to IPv4 address (Websites)
- AAAA: Maps domain to IPv6 address
- MX: Mail Exchange (Dictates email routing)
- CNAME: Aliases one domain to another
- TXT: Text records (Used for SPF, DMARC, verification)
