The concept of proxy IP, what can proxy IP do

When you go online, you will be assigned an IP address before you can go online. This assigned IP address is unique, but people can change their IP address through a proxy IP. So, what does a proxy IP do? Although many people have heard of the term proxy IP, they don't know what it does specifically, nor do they know in which scenarios and industries proxy IP can be applied.

1. What is the proxy IP used for? What is the proxy IP used for? In fact, the proxy IP can be said to be a transit station. When you access the Internet, you connect to the IP proxy on your device, and then access the Internet through the IP address provided by this IP proxy transit station. The role of the proxy IP is not difficult to understand. It uses this transit method to hide the real IP and forward the request. The client sends a request to the proxy server, and the proxy server requests to the target server. In this way, after the target server receives the request, it records the IP address of the proxy server instead of the real IP address. Throughout the whole process, the proxy server is connected to the target server instead of the real client, thereby achieving the purpose of hiding the real IP.

There are also many scenarios for the application of proxy IPs, such as: using proxy IPs for online voting, using proxy IPs to mine data, using proxy IPs for brand monitoring, public opinion monitoring, artificial intelligence, online marketing, and many other scenarios.

2. What are the categories of proxy IP? There are actually three different types of proxy IP, mainly transparent proxy, ordinary proxy, and advanced anonymous proxy. The main difference between advanced anonymous proxy and transparent proxy lies in the difference in the three parameters of REMOTE_ADDR, HTTP_X_FORWARDED_FOR, and HTTP_VIA obtained by the server.

The main difference between these three types of proxies lies in whether the other party's server knows your real IP. When using a transparent proxy, the other party's server will know that you are using a proxy IP and also know your real IP. When using an anonymous proxy, the other party will know that you are using a proxy but do not know your real IP address. With a highly anonymous proxy, the other party does not know that you are using a proxy IP or your real IP address, which means that your real IP is hidden.

Obviously, when using transparent proxy and ordinary proxy, it is easy for the target website to know that you are using the proxy IP, and the IP will be blocked; when the frequency of access to the target website is too fast, the IP will also be blocked, and the access to the IP will naturally be restricted; and the highly anonymous proxy IP can hide the real IP very well, so you can crawl the target website without being restricted.

3. Does the proxy IP have disadvantages? The proxy IP is naturally not perfect, and any product has certain disadvantages. For example, free proxy IPs have some problems such as slow network speed and IP reuse. The speed of using these proxy IPs to access the target website will become very slow, and the connection will be lost from time to time. And the server of the free proxy IP can identify the real IP address, so the free proxy IP is prone to the risk of access information leakage. However, paid proxy IPs are relatively much better, with pure IP resources, a large number of IPs, and faster network speeds. For example, Kookeey can choose hundreds of overseas country IP addresses, which is more convenient and worry-free to use.
