DNS Propagation Checker — frequently asked questions
What is DNS propagation?
DNS propagation is the time frame it takes for DNS record changes (such as updating your nameservers, IP address, or MX records) to update across all global recursive DNS servers worldwide.
Which DNS record types can I query?
You can inspect A, AAAA, CNAME, MX, TXT, NS, and SOA records across all configured global resolver vantage points.
Why do some DNS servers show old records?
Different DNS servers cache records based on the Time to Live (TTL) value set by the domain owner. Until the cached TTL expires, resolvers continue serving existing values.
Can I test private domain names?
No, DNS propagation checks require public domains that are resolvable through public internet DNS root and authority servers.
Are my domain lookup queries logged or tracked?
No, Sada Files does not log, store, or sell queried domain names or IP addresses. All lookups are completely anonymous.
