Web crawlers have always existed on the Internet. Since the emergence of big data, many industries have used web crawlers to collect a large amount of public information for analysis to obtain valuable data. Many people usually need to use proxy IPs . With the development of the times and the advancement of the Internet, many people have begun to realize the importance of proxy IPs. Let's talk about the specific uses of proxy IPs for crawlers.
The purpose of using IP changing software is to collect information by using a large number of IPs. It is like many users are getting information for you at the same time, and using different IP addresses, so that the website will not find that it is a crawler operating. There are also other benefits, that is, when using multiple IPs, the request speed can be set to the speed of normal user browsing, so that it will not trigger website detection, and these IP addresses can be used in a cycle. By operating multiple IPs, you can prevent the IP from being blocked and improve the efficiency of collecting information.
