How to use DNS propagation
-
1
Paste your input
Enter the value at the top — domain, IP, URL, email, ASN, hash, whatever fits this tool. The smart input auto-detects type.
-
2
Click "Inspect"
host.tools issues real probes (DNS, HTTP, TCP, TLS, WHOIS where applicable) and renders the result in milliseconds.
-
3
Open the API tab
Every web tool has a sibling /api/v1/dns/propagation JSON endpoint with the same payload. One copy-as-curl click and you're scripting it.
Why this matters
DNS is the routing layer for everything you do on the internet. A bad TTL, a missing MX or an unsigned zone propagates outages and inboxes-full-of-spam in minutes. Verify before you ship.
API equivalent
/api/v1/dns/propagation?q=stoa.dev.polis.ac
curl -s '/api/v1/dns/propagation?q=stoa.dev.polis.ac'
Embed this tool
<iframe src="/dns/propagation?q={INPUT}&embed=1"
width="100%" height="600" frameborder="0"></iframe>
Drop into any HTML page. The embed=1 flag hides nav and footer.
FAQ · DNS propagation
Common questions
Is DNS propagation free?
Yes — every tool is free on the web with a 200/hour rate limit per IP. The matching API endpoint /api/v1/dns/propagation is free up to 100 requests/hour, no key required.
Where does the data come from?
Real-time probes against authoritative sources (DNS root, RIRs, registries, the target server itself), plus partner data feeds from hostinfo.com (GeoIP/ASN) and hostcheck.com (reputation).
How fresh are the results?
Live by default. Cached for 5 minutes to make repeat queries instant; pass
?nocache=1 for a forced refresh.Can I run this from the command line?
Yes — every tool ships with a copy-as-curl. There's also an official CLI:
host.tools dns propagation YOUR_INPUT.Can I monitor results over time?
Pro tier lets you schedule any tool to run every 1/5/15/60 min and alert on diff. See monitors.
