Check if Your IP Appeared in a Residential Proxy Network

Have I Been Proxied? is a newly released online service that lets users verify whether their IP address or hostname appears on any publicly available proxy or VPN lists. The tool is aimed at individuals and organizations concerned about privacy, security, and compliance, offering a quick way to assess whether their network traffic might be routed through third‑party servers that could expose sensitive data or violate corporate policies.

The service aggregates data from dozens of proxy databases, including both open‑source and commercial lists, and presents the results in a simple web interface. Users can enter an IP or hostname and receive a list of matching entries, along with the source of each listing and the date it was last updated. An optional API endpoint allows automated checks for integration into security monitoring workflows or penetration‑testing scripts.

The launch has attracted modest attention on the Hacker News community, where the discussion page has received 15 points and five comments. Participants in the thread have highlighted the utility of the tool for threat hunting and the importance of maintaining up‑to‑date proxy lists. While the tool has not yet seen widespread adoption, its straightforward functionality and open‑access design suggest it could become a useful resource for network security professionals seeking to identify potential proxy‑related risks.
