What is IP rotation?

IP rotation automatically switches the IP address used for each request or session, distributing your traffic across many different IPs to avoid rate limiting and detection.

How it works: a rotation proxy service maintains a pool of thousands or millions of IP addresses. When your application makes a request, the service routes it through a randomly selected IP from the pool. Some services rotate per request, others maintain a sticky session (same IP for a set duration).

Rotation types: 1) Per-request rotation — every HTTP request uses a different IP. Best for scraping, price monitoring, and data collection. 2) Sticky sessions — the same IP is held for 1-30 minutes. Best for multi-step workflows (login → navigate → action) where maintaining session state requires consistent IP. 3) Geo-targeted rotation — IPs are selected from specific countries or cities. Essential for location-specific data collection.

Implementation: most proxy providers offer rotation as a feature. You connect to a single gateway endpoint, and rotation happens server-side. In your code, you just point your HTTP client at the proxy gateway — no IP management needed.

Cost: $50-$500/month depending on pool size, request volume, and IP quality. Residential rotation costs 5-10× more than datacenter rotation.

Best practices: don't rotate faster than necessary (looks suspicious), match request patterns to normal user behavior, respect rate limits even with rotation, and monitor success rates to detect IP bans early.
