How to use Reverse IP / hosted domains
  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/ip/reverse 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/reverse?q=9.9.9.9
curl -s '/api/v1/ip/reverse?q=9.9.9.9'
Embed this tool
<iframe src="/ip/reverse?q={INPUT}&embed=1"
  width="100%" height="600" frameborder="0"></iframe>

Drop into any HTML page. The embed=1 flag hides nav and footer.

Yes — every tool is free on the web with a 200/hour rate limit per IP. The matching API endpoint /api/v1/ip/reverse is free up to 100 requests/hour, no key required.

Live by default. Cached for 5 minutes to make repeat queries instant; pass ?nocache=1 for a forced refresh.
