Proxy is a technology that hides the real IP address through a proxy server. It can be used to protect user privacy, increase access speed, and bypass network restrictions. Among IP proxies, static IP proxies and rotating IP proxies are two common working principles.

Static IP proxy means that the proxy server uses a fixed IP address for proxying. In this case, the proxy server's IP address is fixed and does not change. When a user sends a request, the request is first sent to the proxy server, which then forwards it to the target website. Since the IP address of the proxy server is fixed, the target website cannot obtain the user's real IP address. This method is suitable for scenarios that require a stable proxy for a long time, such as users who need to bypass regional restrictions or protect privacy.

Rotating IP proxy means that the proxy server uses dynamically assigned IP addresses for proxying. In this case, the IP address of the proxy server is changed regularly to avoid being identified and blocked by the target website. When a user sends a request, the request is first sent to the proxy server, which then forwards it to the target website. Since the IP address of the proxy server is dynamically assigned, the target website cannot track and block the IP address for a long time. This method is suitable for scenarios that require frequent proxy changes, such as users who need to access the target website in large numbers or perform crawling operations.

There are some differences in how static IP proxies and rotating IP proxies work. First, static IP proxies use fixed IP addresses for proxies, while rotating IP proxies use dynamically assigned IP addresses for proxies. Secondly, static IP proxy is suitable for scenarios that require a stable proxy for a long time, while rotating IP proxy is suitable for scenarios that require frequent proxy changes. Finally, static IP proxies are easier to identify and block by target websites than rotating IP proxies because their IP addresses are fixed.

Whether it is a static IP proxy or a rotating IP proxy, they can help users hide their real IP addresses, increase access speeds, and bypass network restrictions. Users can choose a suitable IP proxy method according to their own needs to achieve the required functions.
