When multiple requests are made to a site using the same IP address, the site can mark your IP as a crawler's IP, i.e. an abnormal user, and block your IP or send misleading information so that you can't crawl properly. So regularly changing or switching your IP address can help prevent target sites from identifying your IP as a crawler. Cyclic IP switching can improve the success rate of capture. It can be operated by Proxy Manager software with the IP extracted by RoxLabs:
You can change the number of requests that can be sent before an IP address and the IP switchover interval.
