IP Rotation is the practice of using multiple IP addresses to avoid detection and blocking during web scraping. By frequently changing the IP address from which requests are sent, scrapers can distribute the load and reduce the likelihood of being identified as a bot. IP rotation helps bypass rate limits, access geographically restricted content, and maintain anonymity. This technique is essential for large-scale web scraping operations, where sending numerous requests from a single IP address could result in being blocked by the target website.
