Differences between proxy IP addresses and real IP addresses

In the world of the Internet, we often hear about the concept of proxy IP and real IP, which are two different forms of IP address in network communication. Although they are both used to identify a device's unique location in the network, there are significant differences in use. Let's understand the difference between proxy IP and real IP and their role in the network world.

The real IP address is the public network IP address assigned by the broadband operator to the user, which is the real identity of the user when surfing the Internet. Usually, the real IP is fixed, but sometimes it can change dynamically. When we go online over broadband, our devices are assigned a real IP address, and all network requests and data transfers go through that real IP. The target website can record our real IP address and use it to track our visit.

In contrast, a proxy IP is a kind of transit station, which is actually the IP address of the proxy server. When we use a proxy IP to access a website, our request is first sent to the proxy server, which then forwards it to the target website server. During this process, the target website will record the IP address of the proxy server instead of our real IP address. A proxy IP can be regarded as a virtual IP address that can communicate with a target website in place of a real IP address.

In network communication, there are the following differences between proxy IP and real IP:

1, Identity hiding and protection: Identity hiding and protection is a key advantage of using proxy IP, which plays an important role in protecting user privacy and security in the online world. Real IP is our online identity credentials, through the real IP can track our network activities, including the websites we visit, submit information, browse content, etc. This information is recorded by the target website and may be used for user behavior analysis, advertising recommendations, personalized services and other purposes. However, this may also lead to some privacy security issues, especially in the continuous emergence of data breaches and personal information abuse incidents on the Internet, the exposure of real IP has become an important risk factor.

When using proxy IP, our real IP address is hidden and protected. The proxy server acts as a forwarding station, receiving our network requests and then communicating with the target website on our behalf. The target website can only see the IP address of the proxy server and cannot directly know our real identity and location. The role of this kind of agency is similar to that of entrusting others to transmit information on behalf of others in the real world, and the other party can only see the identity of the agent, but can not know the real source of the information. In this way, our real IP is effectively hidden, and the proxy IP becomes our "avatar" on the network.

②Why can't I access the website when I use a proxy IP

Identity concealment and protection is essential to maintaining personal privacy and security. Especially when using public networks, connecting to untrusted Wi-Fi networks, or accessing sensitive information, the use of proxy IP can effectively reduce the risk of personal information being stolen, exploited, or traced by criminals. In addition, for some network activities that require anonymity, such as network data collection, competitive intelligence collection, and circumventing regional restrictions, the use of proxy IP is very beneficial.

2, restrictions and substitutability: there is usually only one real IP on a line, if our real IP is restricted or blocked by the target website, then we will not be able to continue to visit the website. Proxy IP has more substitutability, when a proxy IP is limited, we can easily switch to another proxy IP, to maintain the continuity of access.

3, stealth and security: The use of proxy IP can increase our stealth and security in the network. The target website cannot accurately determine our true identity and location, thus reducing the risk of being tracked and targeted.

Although proxy IP has advantages in many cases, it is also important to note that some target websites may restrict or block proxy IP, because some malicious users may use proxy IP for illegal activities.

To sum up, proxy IP and real IP have different functions and characteristics in network communication. Proxy IP can protect our real identity and privacy, improve network security and stealth, and also increase flexibility and sustainability in the network. Where appropriate, the use of proxy IP can help us better achieve our goals of network access and data collection.
