What is a proxy IP?

1. What is a proxy IP?

Proxy IP is also called Proxy Server. It is an important security function that can act as a firewall.

Figuratively speaking, a proxy server is a transfer station for network information. It is a server between the browser and the Web server. With it, the request signal will be sent to the proxy server first, and the proxy server will retrieve the information needed by the browser and send it to your browser. In daily life, we use IP proxies, mostly to connect to the INTERNET (internet) and INTRANET (local area network).

2. Functions of IP Proxy

1. Solve network delays and improve operating speed. As a proxy server, it has the function of storage memory. When external information passes through, or the previously requested information is updated, it will be automatically saved in the buffer. When the user accesses the same information again, the buffer can directly take out the information and pass it to the user to improve the access speed.

2. It can be used as a firewall to improve security. Through the proxy server, users can set up IP address filtering to limit the access rights of the internal network to the external network. It can also block IP addresses and prohibit users from accessing certain networks, thus playing the role of a firewall.

3. Hide IP address and protect personal information. There are three types of proxies. Transparent proxy, common proxy, and transparent proxy. Common proxy can hide the user's real IP address and will not be identified as a proxy. Common proxy can hide the user's real IP, but will change the request information so that the other server can recognize that we use a dynamic IP proxy. When using a transparent proxy, the real IP address is still transmitted, and the client does not know the existence of the proxy server at all.

4. Break through the access address restrictions. Many websites will restrict access to users and read the user's IP address through the IP address. Because there is more than one third-party proxy server, users can break through the restrictions by switching the required regional IP.

3. Dynamic IP and Static IP

Dynamic IP corresponds to static IP. In layman's terms, dynamic IP refers to the IP dynamically assigned to netizens when they go online. The IP used each time you go online is different. In contrast, static IP is determined before you go online and is used every time you go online.

Dynamic IP is used to solve the problem of insufficient IP addresses. With the popularization of the Internet, the number of computers used by netizens has increased sharply, and IP addresses are insufficient. Dynamic IP technology came into being. Not everyone is online at the same time, and IPs that are not connected to the Internet are given to those who need them. Similarly, when netizens go online, they will be assigned IPs that are not used by anyone. With the increase in the number of Internet users, technologies such as NAT forwarding have been developed to solve the problem of insufficient IP addresses.

The above is a brief summary of knowledge about proxy IPs. In modern times, the function of IP proxies in protecting user network security has gradually become well known. There are more and more IP proxy software on the market that have met the needs of users, but due to technical reasons, their effectiveness varies.
