Proxy IP is the lifeblood of crawler collection. Crawler cannot proceed without proxy IP support. As websites prevent information loss, the anti-crawler mechanism becomes more and more stringent. When a single IP accesses too frequently and stays for a short time browsing the webpage, it will be immediately restricted from accessing the server. Therefore, crawlers must use a large number of proxy IPs to visit in turn.
Big data is the largest source of information on the Internet. In today's Internet era, eighty to ninety percent of industries are operated online, requiring a large amount of data analysis, so proxy IPs are also widely used.
Many old users know that the proxy IP is the same as our local IP. If the proxy IP is used too frequently and is not changed in time, it will also be restricted and blocked.
We must use it in a standardized manner, not access it frequently, and do not use the IP until it expires or is blocked before changing it. This way of using it will soon find that the available proxy IPs are getting fewer and fewer when using an IP pool. The efficiency of the proxy IP will gradually decrease from the beginning to the middle.
Therefore, a highly anonymous dynamic proxy IP is the best choice for web crawlers, and it fully meets the conditions for the use of crawlers. However, it is recommended that you do not access the dynamic IP too frequently when using it, as it is easy to be restricted. You cannot wait until the proxy IP is restricted before changing it. Although it is a dynamic proxy IP, it must be used reasonably to maximize its effect.
