Proxy lP is also called ProxyServer. It is a key safe and reliable basic function, which can play the role of network firewall. Figuratively speaking, the server agent is a transit station for network information and a network server close to Web pages and web servers. After having it, the request data signal will be sent to the server agent first, and the server agent will retrieve the information needed by the web page and pass it on to your web page. In daily life, people use lP proxy mainly to connect INTERNET and INTRANET.

Second, the basic functions of lP agent

1. Solve the network delay and improve the running speed. As a server agent, it has the basic function of storing memory. When the external information is passed or the previously requested information is updated, it will be automatically saved in the buffer. When the user accesses the same information again, the information can be directly taken from the buffer and sent to the user, which improves the access speed.

2. It can be used as a network firewall to improve security and reliability. Through the server proxy, users can set network ip filters, control the access rights of intranet and extranet, and also shield network ip and prohibit users from accessing certain networks, thus playing the role of network firewall.

3. Hide network ip to protect personal information. Agent types can be roughly divided into three categories. Transparent agent, Bunny agent, transparent agent. Invisible proxy can hide the user's real network ip without being recognized as a proxy. Punic proxy can hide the user's real lP, but it will change the request information and let the other network server recognize that everyone is using a dynamic ip proxy. When the proxy is transparent, the real network ip still passes, and the client simply doesn't know the existence of the server proxy.

4. Break through the access address control. Many websites will control users' access and read users' network ip through network ip. Because there is more than one third-party server agent, users can operate by switching the desired area lP, thus breaking through control. Third, dynamic lP and static IP dynamic lP correspond to static IP. Generally speaking, dynamic lP refers to the lP dynamically allocated by netizens when surfing the Internet. Use a different lP every time you surf the Internet. Corresponding to this is static IP, which has been determined before surfing the Internet, and this lP is applied every time you surf the Internet. The application of dynamic lP is to solve the problem of insufficient network ip. With the popularity of the Internet, the number of computers used by netizens has soared, and the network ip is not enough, so the dynamic lP technology came into being. At the same time, everyone will not be online, and lP without networking will be given to important people. Similarly, netizens will be assigned inapplicable lP when surfing the Internet. With the increase of Internet users, NAT forwarding and other technologies have been developed to solve the problem of insufficient network ip. The above is a brief summary of the knowledge about agent lP. At present, the basic function of lP proxy to protect users' network security is gradually known, and there are more and more lP proxy software on the market, which meets the needs of users. However, due to technical reasons, the efficacy is uneven. Sesame game assistant still advises you not to choose free auxiliary software, which is all sugar-coated shells. We should know that while satisfying the basic functions of lP agent, we should pay more attention to protecting users' privacy and ensuring users' online safety. It is really the best choice for netizens.
