What is the crawler proxy IP? As the name implies, the proxy IP used during crawler work can be called the crawler proxy IP. So, what are the characteristics of the crawler proxy IP? Can all proxy IPs be used for crawling work?
1. High Anonymity Proxy IP is
well known. Proxy IP is divided into three types: Transparent Proxy IP, Common Proxy IP and High Secret Proxy IP. Both transparent proxy IP and Common Proxy IP will reveal that the client is using the proxy IP to access, so it is not applicable. In the crawler work, only the highly hidden proxy IP will not be exposed, such as the use of the Apocalypse proxy covering the country's highly hidden IP resources, so it is suitable for crawler work.
Second, the IP pool is larger, the
crawler task volume is generally larger, and the anti-crawl strategy generally limits the number of requests for a single IP in a unit time. If the IP volume is too small, it is easy to cause work to stagnate, so a larger IP The pool is more suitable for crawler work.
The above are the two most basic features that a crawler proxy IP must have. Of course, there can also be some more high-quality features, such as fast IP speed, high effective connection rate, high business success rate, and good stability. These high-quality features can make Crawlers work more efficiently.
