IPinfo Max

Every flagged IP is directly observed operating as a proxy exit, confirmed by behavior rather than an ASN or hostname guess. Max bundles geolocation, privacy detection, residential proxy, carrier, and connection context in one API. Sign up and start querying the same day.

Self-serve from day one

Named proxy providers

See the specific provider behind an IP, like 711Proxy or ProxyScrape, instead of an anonymous flag, with coverage deep into the long tail.

Recency and frequency

last_seen and percent_days_seen show how recently and how consistently an IP acted as a proxy.

Why Choose IPinfo Max?

Every IP in our residential proxy dataset was directly observed operating inside a proxy network. Membership rests on observed behavior alone: if it's in the dataset, we saw it act as a proxy exit. That is what makes it a signal you can automate on.

Observed in the act

Every IP was seen acting as a residential proxy exit, held to a strict definition of genuinely residential, with mobile and datacenter sub-segments broken out per provider.

Behavior over time

An IP seen once three months ago and one active every day carry very different risk. last_seen and percent_days_seen ship with every IP so you can tell them apart.

Provider attribution

Each IP is tied to the operator running it, with mobile and datacenter pools flagged, so you can weigh a residential exit differently from the same operator's datacenter traffic.

IPinfo Places

Need Places as a data file?

Unrivaled data accuracy

Verified IP Accuracy. Not Estimates.

Most IP providers stop at noisy Whois and geofeeds. IPinfo goes further. We don’t just collect IP data — we verify it, validate it, and engineer it for developers.

They guess. We measure. And that makes all the difference.

Step 1: Collect & Clean

Like most IP data companies, we aggregate raw IP data from multiple sources as a starting point.

Step 2: Learn

Our proprietary algorithms then score and filter 20TB+ of IP data daily to measure accuracy and confidence.

Step 3: ProbeNet Ground Truth

1000+ live PoP’s map IPs around the world in real time, delivering unmatched ground-truth accuracy.

Step 4: Validate

A custom hint engine runs 400B+ weekly checks to verify and confirm every signal for total accuracy.

Step 5: Continual Updates

IP’s change continually… so our data refreshes daily to keep every lookup accurate, stable, and production-ready.

Fast and Easy API Access

Catch the Traffic Other Checks Miss

Fraud Prevention

Flag transactions masked through residential proxies while trusted users pass straight through.

Traffic Quality

Filter proxy-based traffic so campaign analytics and engagement data reflect real visitors.

Threat Intelligence

Surface proxy infrastructure used to hide the origin of malicious activity during investigations.

We feed in a single IP address and get back location, privacy flags like Tor usage, and company or abuse contacts. That has been huge for kicking out malicious logins. In our first week, we caught someone logging in from Kentucky, but the abuse contact was based in Shanghai. This client had zero business in Asia, so we kicked them out in under 200 seconds—far faster than a typical SOC, which can take tens of minutes to hours. We later discovered it was a Russian hacker trying to transfer money. Thanks to IPinfo's data, we were able to stop it within about 90 seconds.

Your Questions, Answered

What is a residential proxy?
A residential proxy routes traffic through a real IP address assigned by an ISP (Internet Service Provider), often a home connection. Because the IP looks like an ordinary user, it gets past detection built only for VPNs, hosting ranges, and datacenter proxies.
How is Max different from Privacy Detection?
Privacy Detection covers VPNs, Tor, public proxies, and relays. Max is a separate dataset built specifically for residential proxies, which are the hardest of the group to catch.
What does percent_days_seen tell me?
It's the share of recent days an IP was observed acting as a residential proxy. Pair it with last_seen to judge whether a sighting is fresh and persistent or stale and occasional.
How quickly can I start?
Same day. You sign up, upgrade to Max, and start querying straight away.
Can I get the data as a database download?
The API is the fastest way to start. Talk to us about database access for higher-volume, offline-matching needs.
How fresh is the data?
The dataset refreshes every 24 hours, so a node that goes quiet drops out of recent activity quickly.
