WorldIP.io is a production-grade IP intelligence platform built and operated by Tuxxin LLC. We map the entire IPv4 Internet — every address, network, and organization — from infrastructure we own and run, not a reseller feed.
Most IP-data providers resell the same handful of geolocation databases. We take the opposite approach: a globally distributed scanner fleet across North America, Europe, and Asia-Pacific continuously resolves reverse and forward DNS across all 4.3 billion IPv4 addresses. The data is first-party, kept fresh in near real time, and served as clean JSON in under a second. Our fourth-generation scanner engine is built to complete a full pass of the IPv4 space in under 24 hours.
The platform runs the way a production service should — replicated across regions, continuously monitored, and engineered for accuracy at scale. A free public site sits on top of it, plus a keyless public API that is live today — call it from a single curl https://worldip.io/8.8.8.8 — and enriched, higher-volume subscription plans (VPN/proxy and datacenter classification, trust scoring, and live BGP) for teams that need more. New data products ship on a steady cadence. For a live look at the platform, see our infrastructure status page.
WorldIP speaks MCP: IP intelligence as a tool, no key required
Aug 20, 2026 by Tuxxin
WorldIP.io is an MCP server, so an AI assistant can look up network
attribution directly instead of scraping pages or guessing.
Endpoint: https://worldip.io/mcp (JSON-RPC 2.0, HTTP POST)
Tools: lookup_ip(ip) - full public profile for an IPv4 address
whats_my_ip() - the caller's own address and profile
Auth: none. 1,000 requests/day and 60/min per IP.
Client config:
{ "mcpServers": { "worldip": { "url": "https://worldip.io/mcp" } } }
You get PTR and forward DNS with FCrDNS match status, owning organisation,
ASN, country, region, city, allocation range and last scan time. First-party
scanner fleet, not a resold dataset.
Every IP page also serves JSON directly, no key and no signup:
curl https://worldip.io/8.8.8.8

Upgraded IPv4 Scanner Delivers 10x Speed Boost, Paving the Way for Expanded IPv6 Datasets
Aug 3, 2026 by Tuxxin
We are excited to announce the release of Version 4 of our IPv4 scanning engine, delivering a 10x increase in scan capacity. With this performance leap, our infrastructure now completes full scans of the assigned IPv4 address space in roughly 24 hours—with the ability to scale our global network further to bring scan times down to mere hours.
Building on this milestone, we are porting the updated scanner architecture into Version 2 of our IPv6 scanner. We have been actively collecting IPv6 data for over a month and will be releasing the full datasets once comprehensive coverage is achieved.
Stay tuned for further updates as we continue expanding our global data coverage.
