Rotating Proxy
BeginnerA proxy setup that automatically assigns a different IP from a pool for every request or at set intervals, spreading traffic across many identities.
In depth
A rotating proxy is less a kind of IP than a way of using them. Instead of sending all traffic through one address, you connect to a single gateway endpoint and the provider swaps the exit IP behind it — per request, per few minutes, or on demand. To the target, one crawler becomes thousands of unrelated visitors.
How it works
You configure one hostname and port (for example gateway.provider.com:7777). Each request the gateway receives is mapped to a different IP drawn from the provider's pool — residential, datacenter, ISP or mobile depending on the product. Rotation policy is usually controlled with credentials or session parameters: append a session ID to keep an IP, omit it to rotate every request.
Why rotation matters
- Rate-limit evasion: per-IP request budgets stop applying when every request has a new IP.
- Block absorption: a banned IP costs nothing; the next request already uses a different one.
- Scale: rotation is what lets a single scraper make millions of requests per day plausibly.
Trade-offs
Rotation breaks anything that depends on continuity — logins, carts, multi-step forms — unless you pin a sticky session. Quality also varies per exit: one bad pool IP can poison a request, so production scrapers pair rotation with retries and response validation.
Examples
- A scraper collects 2 million product pages in a day, each request exiting from a fresh residential IP.
- A SERP tracker queries Google for 50,000 keywords, rotating IPs so no address sends more than a handful of searches.
- A monitoring bot rotates through a datacenter pool every 5 minutes to keep a long crawl under per-IP rate limits.
Common use cases
FAQs
Rotate for breadth: anonymous, high-volume reads where each request is independent. Stay static for depth: logins, accounts and anything stateful. Many workflows use both — rotating for discovery, static for the authenticated steps.
Per-request rotation maximizes anonymity for stateless scraping. Timed rotation (1–30 minutes) suits crawls that need brief continuity. The right answer is the longest interval that stays under your target's per-IP tolerance.
They reduce IP-based triggers, but modern defenses also score browser fingerprints and behavior. Pair rotation with realistic headers, pacing and — for hard targets — fingerprint management to keep challenge rates low.
