Proxy IP is widely used in various industries, such as network voting, effect supplementation, and data mining. To switch to using a proxy IP, one way is to restart the router or optical modem, but this is a cumbersome method. Another way is to buy a dial-up VPS, which allows you to switch an IP address every time you dial it. Browsers with proxy IPs are also popular, but it can be cumbersome for users who need to switch IP addresses frequently. The MaxProxy tool is a popular choice as it can change the IP address of the entire computer and supports the use of HTTP and socks5 proxy IPs, but switching IP addresses requires manual copying of proxy and port information and setting up switching.
