Identity Digital Australia Pty Ltd, for itself and on behalf of .au Domain Administration Limited (auDA), makes the WHOIS registration data directory service (WHOIS Service) available solely for the purposes of:

(a) querying the availability of a domain name licence;

(b) identifying the holder of a domain name licence; and/or

(c) contacting the holder of a domain name licence in relation to that domain name and its use.

The WHOIS Service must not be used for any other purpose (even if that purpose is lawful), including:

(a) aggregating, collecting or compiling information from the WHOIS database, whether for personal or commercial purposes;

(b) enabling the sending of unsolicited electronic communications; and / or

(c) enabling high volume, automated, electronic processes that send queries or data to the systems of Afilias, any registrar, any domain name licence holder, or auDA.

The WHOIS Service is provided for information purposes only. By using the WHOIS Service, you agree to be bound by these terms and conditions. The WHOIS Service is operated in
accordance with the auDA WHOIS Policy (available at https://www.auda.org.au/whois-policy).
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=donate.uiaaustralia.org.au

Embed this tool
<iframe src="/domain/whois?q={INPUT}&embed=1"

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.
