Privacy Detection API

Privacy Detection API

Our Privacy Detection API detects various methods used to mask a user's true IP address, including VPN detection, proxy detection, tor, relay usage, or a connection via a hosting provider, which could potentially be used to tunnel traffic, and mask the true IP address.

  • vpn:true,
  • proxy:false,
  • tor:false,
  • relay:false,
  • hosting:true,
  • service:"",

We needed to further contextualize Internet scanners, crawlers, and bots. Origin networks, data centers, ASNs, and countries are a huge component of that. We were looking for a faster, more developer-friendly alternative to existing geo-IP providers. A close friend of mine hit the IPinfo API with cURL, and I saw all the information we needed.

Accurate & up-to-date
privacy detection data

We perform custom full internet wide scans to detect almost 10 million active VPNs. This is combined with data on public SOCKS and HTTP proxies, tor exit nodes, and our own IP usage type classification to determine which IP ranges belong to hosting providers. The data is updated regularly, so the results are always fresh.

  • Relay
  • Proxy
  • Hosting

Frequently Asked Questions

How do Anonymous or Masked IPs work?

IP address users can mask their identity by using a VPN, a proxy, tor nodes, relay usage, or hosting providers.

What is a VPN, proxy, or tor node?

A VPN is a virtual private network. Both VPNs, proxies, and tor nodes protect a device’s website connection and privacy by spoofing its geolocation.

How does Apple Private Relay work?

Apple Private Relay hides some IP details but is still geo-aware. This means you can use the geolocation details for website personalization, streaming restrictions, threat intelligence, and more.

How do you differentiate between location-aware and masked IPs?

Our API response has a separate classification for Apple Private Relay to help users differentiate between geo-aware and masked IPs.
