The Proxy Auto-Configuration URL
One of the easiest ways to change your ip address with a proxy server is by using a proxy auto-configuration url in your web browser. A proxy auto-configuration url tells your browser when to use a proxy server, and what proxy server hostname and port to use.

How do I use a Proxy Auto-Config URL with an Authenticated Proxy Server?
Because proxy auto-configuration urls do not support specifying proxy usernames and password (and for good reason, because it would be a security risk), you must use IP address authentication. ProxyMesh supports address IP authentication for its rotating proxy server, which you can configure after you signup for ProxyMesh. Once your IP is registered with the proxy server, then the proxy auto-config will handle the rest, by specifying the proxy server hostname and port for each request.
How do I setup Automatic Proxy Configuration?
Once you have a url to auto-config the proxy, you must go into your browser's proxy or network settings and look for Automatic proxy configuration, Autoconfiguration url, Automatic proxy configuration url, or PAC File URL, and copy/paste the url. Once you save this url in the settings, your browser will be using the automatic proxy configuration for all future requests.
