This article mainly introduces "what are the functions of proxy IP". In daily operation, I believe many people have doubts about the functions of proxy IP. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the functions of proxy IP?" Next, please follow the editor to study!

What is the proxy IP

A proxy IP is also known as a proxy server. It is an important security function and can play the role of firewall. It is a server between a browser and a web server. With it, the Request signal will first be sent to the proxy server, which will retrieve the information needed by the browser and send it to your browser. In daily life, we mainly use IP agents, most of which are used to connect INTERNET (Internet) and INTRANET (LAN).

What are the functions of proxy IP

1. Break the access address restriction. Many websites restrict access to users, reading users'IP addresses through IP addresses. Since there is more than one third-party proxy server, users can operate by switching the desired regional IP, thus breaking the limit.

two。 Solve the network delay and improve the running speed. As a proxy server, it has the function of storing memory. When external information is updated or previously requested, it is automatically saved in the buffer When the user accesses the same information again, the buffer can directly take out the information and transmit it to the user to improve the access speed.

3. Hide IP addresses and protect personal information. The types of agents are roughly divided into three categories. Transparent agent, Punic agent, transparent agent. A high-hiding agent can hide the user's real IP address instead of the agent. A normal agent can hide the user's real IP, but it will change the request information so that the other party's server recognizes the dynamic IP agent we are using. Transparent proxy, the transmission is still the real intellectual property address, the client does not know the existence of the proxy server.

4. Can be used as a firewall to improve security. Through the proxy server, users can set IP address filtering, restrict the access of the internal network to the external network, or block the IP address and prohibit users from accessing some networks, thus acting as a firewall.

Third, the principle of proxy IP: the principle of proxy IP is equivalent to the "transit station" connecting the client and the remote server.

When we send a request to the remote server, the proxy server first obtains the user's request, then forwards the service request to the remote server, and then forwards the result of the server feedback to the client remotely. This is equivalent to saying that the server is processing the server, which is hidden behind the scenes.

At this point, the study on "what are the functions of proxy IP" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
