How to use IP WHOIS
-
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/ip/whois JSON endpoint with the same payload. One copy-as-curl click and you're scripting it.
Why this matters
Every IP tells a story — what network it lives on, who owns it, where it sits, whether it's been used for abuse. The smartest decisions about traffic start with a 30-second IP review.
API equivalent
/api/v1/ip/whois?q=1.1.1.1
curl -s '/api/v1/ip/whois?q=1.1.1.1'
Embed this tool
<iframe src="/ip/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 · IP WHOIS
Common questions
Is IP WHOIS free?

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
