Many websites today limit the acceptable number of requests sent within a specific time period to prevent their sites from being spam. If you attempt to send more than the acceptable amount, your access to the site will be denied. Use proxies at this time, and then rotate them every once in a while so that you can continue to access the website. So, what does IP address rotation mean?
For web scraping and other forms of automation, you need to use multiple IP addresses to avoid being banned. You can achieve this through IP address rotation. IP rotation is the process by which the IP address assigned to your web request changes after each request or after a given period of time. The rotation proxy is responsible for IP rotation itself. When you choose to use a rotating proxy IP, you don't have to rotate the IP yourself. You can stop IP rotation when you don't need to change the IP.
If you need to exceed request limits or operate multiple accounts on the same system, you must rotate proxies or you will be banned.Rotating proxies are very suitable for Python crawlers and can improve the efficiency of crawlers.
