Differences between the three attributes of the user IP address (http_x_forwarded_for, http_via, rem_addr

1. If no proxy server is used: remote_addr = Your IP http_via = no value or no http_x_forwarded_for = no value is displayed. 2. When a transparent proxy server is used: transparent proxies remote_addr = The Last Proxy Server IP http_via = the Proxy Server IP http_x_forwarded_for = your real IP address. When you pass through multiple proxy servers, the value is similar to: 203.98.182.163, 203.98.182.163, and. This type of proxy server still forwards your information to your access object, which cannot hide your real identity. Iii. Normal anonymous proxy server: anonymous proxies remote_addr = last Proxy Server IP http_via = Proxy Server IP http_x_forwarded_for = Proxy Server IP, when multiple proxy servers pass through, this value is similar to the following: 203.98.182.163, 203.98.182.163, 203.129.72.215. Your real IP address is hidden, but you are disclosed to the access object that you use the proxy server to access them. Iv. Use of fraudulent proxy servers: distorting proxies remote_addr = Proxy Server IP http_via = Proxy Server IP http_x_forwarded_for = random IP address. When multiple proxy servers are used, this value is similar to the following: 203.98.182.163, 203.98.182.163, 203.129.72.215. It tells the access object that you used the proxy server, but fabricated a false random IP address instead of your real IP address to cheat it. 5. Use of highly anonymous proxy servers: High anonymity proxies (elite proxies) remote_addr = Proxy Server IP http_via = no value or no display of http_x_forwarded_for = no value or no display, when multiple proxy servers are used, the value is as follows: 203.98.182.163, 203.98.182.163, 203.129.72.215. The proxy server information replaces all your information, just as you directly access the object using the proxy server.
