Free Live DNS Change Monitor & Propagation Polling

Real-Time Baseline Detection & Un-cached DoH Tracking

Track critical DNS updates and global propagation exactly as they happen in real-time. We execute continuous, un-cached DNS over HTTPS (DoH) polling to bypass local ISP delays, giving you an immediate, live feed of your domain's routing state. Guaranteeing absolute technical accuracy with strictly real-time operations and zero simulated data, our backend automatically detects baseline deviations and precisely matches your expected target records, logging an exact chronological timeline so you can execute zero-downtime migrations with complete confidence.

DNS Update & Propagation Tracker

Waiting for a DNS change to propagate? Enter your domain and we will poll global resolvers continuously, alerting you the exact second your new IP or record goes live.

Why Use Our DNS Change Monitor?

Don't waste time constantly hitting refresh. Start the monitor, sit back, and let our system track the exact moment your critical DNS migrations propagate through the global network.

Continuous Live Polling

Executes automated, un-cached DoH queries at your requested interval (as fast as 5 seconds), giving you a real-time feed of your domain's routing state.

Baseline Detection

Automatically detects your current "old" DNS value upon starting. The monitor watches this baseline and alerts you the instant it deviates, indicating a propagation event.

Expected Target Matching

Input your specific new server IP or MX hostname. The tracker will specifically look for this value to appear, confirming that the correct update has been applied globally.

Historical Timeline Log

Maintains a scrolling chronological history of every single poll attempt. You can clearly trace the exact second a value flipped from the baseline to the target.

No Local Caching Delays

Standard command-line tools like 'ping' or 'nslookup' rely on your local ISP cache, which can take hours to update. Our DoH backend bypasses this entirely for instant results.

Migration Safety

Crucial for zero-downtime migrations. Don't shut down your old server until our monitor confirms that the new DNS routing has fully taken effect on Tier-1 resolvers.

Done!
