IP rotation is a cybersecurity practice where the IP address used by a device, server, or proxy is changed at regular intervals or after a certain number of requests. This technique helps avoid detection, blocking, or rate-limiting by websites and online services. It is commonly used in web scraping, penetration testing, and when accessing geo-restricted content. By rotating IP addresses, users can distribute their requests across multiple identities, reducing the risk of being blacklisted or flagged for suspicious activity. However, improper use of IP rotation may violate terms of service or legal regulations.
