Have I Been Proxied? - Check your IP reputation

Have I beenproxied? Find out in one click. Check whether your public IP has been observed in a residential proxy network, and
understand what to do next. Check my IP We check the public IP address your browser is connecting from. Nothing is installed, and we
do not scan your devices. [ Why check your IP? ] Your connection.Someone else's traffic. Residential proxy networks route internet traffic through IP addresses tied to real
household connections. Apps, browser extensions, VPNs, smart TVs, or other connected devices can make your home network part of a proxy network without
your knowledge. We check for signs that a proxy service has used your internet connection to send other
people's traffic. If we find any, we'll explain what we found and suggest which apps and
devices to check. 01 Check your public IP Start with the public IP your browser is using.02 See what we have observed See whether your IP has been observed in a residential proxy network.03 Know what to investigate next If activity is found, get guidance on where to look and what to do next. [ For fraud & trust teams ] The intelligence behind the check. Have I Been Proxied is powered by Spur Intelligence, which helps security and fraud teams

The service offered allows users to check the reputation of their public IP address to determine whether it has been observed within a residential proxy network. This process focuses solely on the public IP address used by the browser and explicitly states that the service does not install software or scan the user's devices. The underlying rationale for performing this check stems from the fact that residential proxy networks route internet traffic through IP addresses associated with genuine household connections. This context highlights a potential security concern: applications, browser extensions, VPNs, or smart devices can inadvertently integrate a home network into a proxy network without the user's awareness. Therefore, the system checks for evidence that a proxy service has utilized the user's internet connection to transmit other individuals' traffic.

The methodology for checking IP reputation involves a three-step process. First, the user initiates the check using the public IP address currently being used by their browser. Second, the system reviews the observations made regarding that IP to determine if it has been flagged as observed in a residential proxy network. Finally, if any activity related to proxy usage is detected, the service provides guidance on areas to investigate and recommended next steps for remediation.

The intelligence driving this check is derived from Spur Intelligence, which is utilized by security and fraud teams to identify various forms of hidden network activity. This intelligence assists in detecting residential proxies, VPNs, anonymization infrastructure, and other obscured network operations across enterprise systems and applications. Essentially, the tool aims to reveal hidden connections and traffic routing anomalies by analyzing the observed network behavior.
