The public proxy servers in our IP Changer list are tested continuously to ensure the proxies listed here are still active. You can further narrow down the pre-selected list of proxies by using the self-explanatory proxy selection box below. For example, checking only the "HTTPS" proxy box will filter the list to only show SSL proxies. Increasing the number of selection rules will generally result in a smaller population, but our public IP changer list database is quite large so you should always have a sufficiently extensive list for your purposes. In certain cases you may have to adjust the selection rules in order to strike a balance between the number of proxies returned and the selection criterion you want.
