Proxy IPs are commonly utilized in various network-related fields, such as network voting, effect implementation, data mining, and others. However, many inexperienced users may find it challenging to use and switch proxy IPs. Here are several methods for switching to a proxy IP:

One way to change the public IP address is by restarting the router or optical modem. Dial-up Internet access causes the public IP address to change every time the router is restarted. If the router uses a static IP address on the external network, restarting the optical modem is necessary to change the public IP. Although this method can change the computer's public IP for Internet access, it is a cumbersome process and is not widely used.

Another option is to buy a dial-up VPS. By connecting remotely, you can switch IP addresses every time you dial. You can opt for a mixed VPS that dials out random IPs across the country, or a single-region dial-up VPS that dials out a specific region's IP. This method is more convenient than restarting the optical modem, but it only allows you to use one IP address at a time.

Browser-based proxy IPs are also a popular option. By changing the browser's proxy IP settings, you can change the browser's IP address, which is useful for accessing specific websites. However, this method may not be ideal for users who need to frequently switch IP addresses, as it can be time-consuming.

Finally, many people use the MaxProxy tool to change the entire computer's IP address. It supports HTTP proxy IP and socks5 proxy IP, making it a powerful tool. However, switching IP addresses still requires manual copying of proxy and port information and setup, which can be cumbersome.
