IPChecker

IPChecker is a powerful IP address detection tool, which can help users to determine whether a given IP address is a Tor node or a malicious open proxy. By integrating multiple plug-ins, this tool obtains proxy IP from public sites and stores it in the database. Users can query these IP addresses through API. The working mechanism of IPChecker includes starting the Docker service to run the API, and communicating through the Docker network named ipchecker-network, exposing only port 8080. In order to avoid false positives, the API only returns the IP address of the current date, because proxy servers or Tor nodes usually use dynamic IP. To use IPChecker, you first need to install and configure the Python environment on the local device, and then clone the project source code locally through Git. Next, you can use Docker to install and run IPChecker. Service execution command options include building all images, building and running all images, terminating all services, and terminating services and cleaning up images and MongoDB data.  The basic usage methods of IPChecker include obtaining documents through API nodes, obtaining statistical information, searching a single IP address in the database and returning all IP information in the database. The development and release of this tool follows the MIT open source license agreement, and the project source code can be found on GitHub. In addition, there are other ways to judge whether an IP address is a proxy, such as using reverse detection technology, checking X-Forwarded-For and Keep-alive messages in the HTTP header, and checking the ports on the IP. These methods can help users identify proxy IP and take corresponding network security measures. If you need to check whether the IP address is blocked or available, you can also use online tools to detect it.
