        **What is Distorting Proxy?**

        A Distorting Proxy is a type of anonymous proxy server that hides the user’s real IP address but sends a **false IP address** to the destination server. It intentionally provides misleading identity information.

        **Why is Distorting Proxy useful?**

        * Helps conceal the user’s real IP address.
        * Provides an extra layer of privacy by misrepresenting the origin of the request.
        * Useful in bypassing geo-restrictions or censorship by faking location data.
        * Can be used in cybersecurity research or to test geolocation features.

        **How it works?**

        * The user sends a request to the distorting proxy.
        * The proxy forwards the request to the destination server while:
          * **Hiding the real IP address**.
          * **Inserting a fake IP address** in the `X-Forwarded-For` or similar HTTP headers.
        * The destination server believes the request is coming from the fake IP.

        **Where is Distorting Proxy used?**

        * In privacy-focused web browsing tools.
        * For bypassing IP-based filters or restrictions.
        * By testers and researchers simulating user traffic from different locations.
        * Occasionally used in corporate environments for anonymizing internal traffic.

        **Which OSI layer does this protocol belong to?**

        * Distorting proxies operate at the **Application Layer (Layer 7)** of the OSI model.
        * They work by modifying HTTP headers and interacting with web applications.

        **IS Distorting Proxy windows specific?**

        * No, Distorting Proxy is not Windows-specific.
        * It can be configured on any platform that supports proxy server software (e.g., Squid, Nginx, Apache).

        **IS Distorting Proxy Linux Specific?**

        * No, it is not Linux-specific.
        * Though commonly deployed on Linux-based servers, it is platform-independent and runs on Windows, macOS, and BSD as well.

        **Which Transport Protocol is used by Distorting Proxy?**

        * Typically uses **TCP**.
        * Most often operates with **HTTP** or **HTTPS**, which are built on top of TCP.

        **Which Port is used by Distorting Proxy?**

        * Commonly used ports:
          * **Port 80** for HTTP.
          * **Port 443** for HTTPS.
        * Some custom proxy setups may use **port 3128**, **8080**, or others depending on configuration.

        **Is Distorting Proxy using Client server model?**

        * Yes, it follows the **client-server model**.
        * The client (user) sends requests to the proxy server, which then relays the request to the destination while modifying identifying information.
