What is IP Rotation?
IP rotation is a technique where automated systems cycle through a pool of IP addresses, assigning a different IP to each request or group of requests. This prevents any single IP from sending too many requests to a target server, reducing the risk of being blocked or rate-limited.
How IP Rotation Works
An IP rotation system typically consists of:
Rotation Strategies
Different use cases call for different rotation approaches:
Legal and Ethical Considerations
IP rotation itself is a neutral technical practice. However, using it to circumvent terms of service, bypass security measures, or mask malicious activity raises ethical and legal concerns. Always ensure your automation complies with the target website's terms and applicable data protection regulations.
なぜ重要か
IP rotation is a critical technique for maintaining reliable access in large-scale web scraping and automation. Without it, concentrated traffic from a single IP address quickly triggers anti-bot defenses, CAPTCHAs, and permanent bans.
Autonolyのソリューション
Autonoly runs each automation session in an isolated container with its own network identity. For workflows that require sustained access to external sites, the platform manages IP diversity automatically through its containerized infrastructure, so you do not need to configure or maintain proxy pools.

よくある質問
How many IP addresses do you need for effective rotation?
It depends on scale. For moderate scraping (a few thousand requests per day to a single domain), 50-100 IPs may suffice. For high-volume operations, thousands of IPs are common. The key metric is requests per IP per time period — you want each IP to stay well below the target site's detection thresholds.
What is the difference between IP rotation and a proxy pool?
A proxy pool is the collection of proxy servers (each with its own IP). IP rotation is the strategy for cycling through that pool. You need a proxy pool to perform IP rotation, but having a pool alone does not mean you are rotating — you also need the logic to select and switch between proxies.
