At present, agents have important security. Generally speaking, the network information transfer station is a kind of proxy server, which is between the browser and the network server. With it, the Request signal will first be sent to the proxy server, which will find the information you need and quickly send it to your server. IP proxy is used daily, mainly to connect INTERNET and INTRANET.

That is to say, when you visit a website, you will leave your IP, but proxy IP means that when your IP is left behind, its function is:

1. Solve the network delay and improve the running speed.

Like a proxy server, it has the function of storing memory. If the external information is passed, or if the previously requested information is updated, it will be automatically saved to the buffer. When the user makes the same request again, they will get the information directly from the buffer and return it to the user to improve the access speed.

2. Firewall can be installed to improve the security of the system.

With a proxy server, users can implement firewall functions by setting ip address filtering, restricting internal network access to external networks, blocking ip addresses, and forbidding users from accessing certain networks. Hide ip addresses and protect personal information.

3. The types of agents are roughly divided into three categories: transparent agents.

The ① High Hidden Agent can hide the user's real IP address, but is not recognized as an agent.

The ② hiding agent can hide the user's real IP, but it will change the request information. Let's look at each other with a dynamic IP agent.

③ in a transparent proxy, the real IP address is still being transmitted, and the customer has no idea that the proxy server exists.

4. Break through the address access restriction.

Many sites restrict user access and obtain IP addresses through IP addresses. In this way, a third-party proxy server has been added, and users can break through the limit by switching the desired zone ip.
