An IP scrambler is a tool that hides your IP address by using proxy servers to route your requests to target web servers. Instead of your IP address, the target web server would detect the IP address of the proxy server that you are using. An IP scrambler can be achieved by using rotating proxies that automatically change their IP address after each web request.
The significant difference between an IP scrambler and a proxy is that the former uses a proxy every time you connect. However, it will be a different proxy in each instance of a new connection, making it more like rotating proxies. As a result, experts often prefer IP scrambler more than a typical proxy and often call it a proxy switcher.
