This article mainly introduces the reptiles generally use which agents ip, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Crawlers generally use highly anonymous agent ip. Because reptiles need high concealment, only agents with high concealment and security, that is, high concealment agents, are suitable for use by reptiles.

Crawlers generally use highly anonymous agent ip.

In the process of collecting information, the crawler will send out a large number of requests in a short time, occupy the bandwidth of the server, affect the access of normal users, and seriously lead to website paralysis. In order to ensure the normal access of users, the website will turn on anti-crawling measures, and the IP of the crawler will be blocked and cannot continue to crawl.

An easy way to keep the crawler working is to change the crawler's IP, and the best way to change the IP is to use the proxy IP.

However, there are many types of proxy IP, and not all proxy IP is suitable for crawlers. Because reptiles need high concealment, only agents with high concealment and security, that is, high concealment agents, are suitable for use by reptiles.

The highly anonymous agent does not change the client's request, so it looks to the server as if a real client browser is accessing it, when the client's real IP is hidden and the server will not think we are using the proxy.
