When a user chooses to use a residential proxy, his or her network request will first pass through the proxy server. The proxy server has one or more residential IP addresses that originate from real home users. These addresses are the same as the IP addresses used by regular home users, so they are not easily identified as proxies by the target website. When the user's request reaches the proxy server, the proxy server will forward it to the target website, using its own residential IP address as the source of the request. In this way, the target website can only see the residential IP address of the proxy server, but cannot obtain the user's real IP address. The advantage of residential proxies lies in their high anonymity and low latency, which can provide flexible network access methods and protect user privacy and security.
