How to use Domain WHOIS
  1. 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. 2
    Click "Inspect"

    host.tools issues real probes (DNS, HTTP, TCP, TLS, WHOIS where applicable) and renders the result in milliseconds.

  3. 3
    Open the API tab

    Every web tool has a sibling /api/v1/domain/whois JSON endpoint with the same payload. One copy-as-curl click and you're scripting it.

Why this matters

WHOIS, expiry, DNSSEC, name servers — domain metadata is the single most-overlooked outage source. Lock it down before someone else does.

API equivalent
/api/v1/domain/whois?q=1x.nu 
curl -s '/api/v1/domain/whois?q=1x.nu'
Embed this tool
<iframe src="/domain/whois?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 · Domain WHOIS

Common questions

Is Domain WHOIS free?
Yes — every tool is free on the web with a 200/hour rate limit per IP. The matching API endpoint /api/v1/domain/whois 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 domain whois 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.
