Proxy IP plays a key role in network data fetching and crawling tasks, especially high-hiding proxy IP, which can completely hide the user's real IP address, so as to achieve the purpose of protecting secure access and circumventing restrictions. However, some users have found that they are still restricted despite the use of high hiding proxy IP, which raises the question: Why can't High hiding proxy IP completely avoid restricted access? We'll take a closer look at why.
1. Confirm whether it is a high secret agent
Confirming whether the proxy IP is a high hidden proxy is a crucial step when using a proxy service. Although proxy providers claim to offer highly anonymous proxy IP, in fact, not all proxy IP can be truly highly anonymous, which may include ordinary anonymous proxy or transparent proxy. Users should be very careful when choosing proxy service providers to ensure that the purchased proxy IP really has high hiding characteristics, so as to avoid access restrictions.

2. The proxy IP address usage is low
Low usage of proxy IP addresses indicates that proxy IP addresses in the shared proxy IP address pool are used by multiple users. In this case, the same proxy IP address may be used by multiple users to access the same destination website. While the shared proxy IP pool provides users with a certain degree of convenience and economy, it also brings some potential problems.
When the proxy IP usage is low, that is, multiple users use the same proxy IP address to access the same website at the same time, abnormal traffic patterns occur. This abnormal traffic pattern may attract the attention of the target site server, making it suspect that these proxy IP may be performing abnormal access behavior, such as crawling data, batch access, and so on. In order to protect the stability and security of the server, the target site server may take measures such as blacklisting these proxy IP addresses, restricting their access, or even denying them access altogether.
In this case, users' access is also affected. After IP resources in the proxy IP address pool are restricted, users may not be able to access the target website successfully. As a result, normal services of users are affected. In addition, the quality of proxy IP addresses in the shared proxy IP address pool varies. Some IP addresses may have been frequently used by multiple users, which may degrade their performance or even make them unavailable.
3. The request frequency is too high
Excessive request frequency means that in the crawler task, the user sets too frequent requests, that is, sends a large number of requests per unit time to obtain data. Although such behavior can speed up the speed of data acquisition, it may put great pressure on the server of the target site, affecting its normal operation.
For the target site server, the task of processing a large number of frequent requests consumes a lot of computing resources and bandwidth, which can lead to heavy server load, slow response times, and even service crashes. In the face of this unusual request pattern, the target site server usually takes measures to protect its own stability and security, one of which is to limit the frequency of access to the same IP.
Even if the user uses a high-hiding proxy IP to hide the real IP address, it is still possible for the target site server to detect an exception if the request frequency is too high. This is because a high frequency of requests can exhibit an unnatural pattern, without the randomness and irregularity of real users. This regular pattern is easily recognized by the target site server as crawling behavior, thus blacklisting the proxy IP, restricting its access rights, or even denying its access entirely.

4. Request patterns are too fixed
The request pattern of some crawlers is too fixed, and each request takes exactly the same time, showing very regular access behavior. Even with high-hiding proxy IP, this regular behavior is easily detected by the target site server and recognized as crawler behavior, thus restricting access.
In order to avoid restricted access to high-hiding proxy IP addresses, users should choose a trusted proxy service provider to ensure that the proxy IP provided is high-hiding and stable. At the same time, when the proxy IP is used, the request frequency is set reasonably, and the access behavior of real users is simulated in random mode, so as to improve the diversity and unpredictability of access, so as to better protect the secure access and successfully complete the crawling task.
