Questions & Answers

As answered by people managing IPLogs.
  1. What makes IPLogs unique?

    IPLogs combines multiple detection methods instead of relying on a single IP blacklist. It uses IP intelligence, TCP/IP and TLS fingerprinting, RTT analysis, active VPN protocol probing, client signals, and network checks to detect VPNs, proxies, Tor, and datacenter IPs. It also shows the individual signals behind every verdict, supports IPv4 and IPv6, and provides a free API without signup or an API key.

  2. Why should a person choose IPLogs over its competitors?

    IPLogs is free to use, requires no account or API key, and provides transparent detection results instead of only returning a black-box risk score. Developers can see which signals and sources triggered a detection, use both IPv4 and IPv6, perform bulk IP checks, and integrate the REST API directly into their applications.

  3. How would you describe the primary audience of IPLogs?

    IPLogs is primarily built for developers, security teams, SaaS companies, fraud-prevention teams, website owners, and researchers who need to identify VPNs, proxies, Tor exits, datacenter IPs, or suspicious network traffic. Common use cases include fraud prevention, account security, abuse detection, geo-restriction enforcement, and network analysis.

  4. What's the story behind IPLogs?

    IPLogs was created after finding that many VPN detection APIs marketed as free still required signup, imposed restrictive limits, hid detection signals behind paid plans, or produced unreliable results for services such as Apple Private Relay. The goal was to build a simple IP intelligence service that developers could use immediately without an account or API key, while also showing exactly why an IP was classified as suspicious. IPLogs launched in early 2026 and is developed by DigitalD.tech.

  5. Which are the primary technologies used for building IPLogs?

    Go, Next.js, Caddy, REST API, Hetzner Cloud
