❓ Frequently Asked Questions
What is the DNS Propagation Checker used for?
Compare a domain's A record across multiple public DNS resolvers.
Is the DNS Propagation Checker free and private?
Yes — it's free with no sign-up. The DNS Propagation Checker queries public network services (such as DNS or WHOIS) directly from your browser to fetch live results; IP Ducky never logs or stores what you look up.
Do I need to install anything to use the DNS Propagation Checker?
No. It works in any modern web browser on desktop, tablet, or phone — no downloads, no browser extensions, and no account required.
