IP Rotation

The practice of cycling through multiple IP addresses across requests so no single IP triggers rate limits or bans.

IP rotation is the technique of distributing outbound scraping requests across many different IP addresses rather than sending all traffic from one origin. The goal is to stay below the per-IP rate limits and ban thresholds that anti-bot systems enforce.

Effective IP rotation uses diverse IP ranges — mixing residential, mobile, and datacenter addresses — combined with realistic request timing that mimics human browsing patterns. Simply switching IPs is not enough if all IPs share the same ASN (Autonomous System Number), TLS fingerprint, or user agent: correlation attacks can link the requests back to a single actor despite the IP change.

AlterLab handles IP rotation transparently at the infrastructure layer. Developers do not manage proxy pools, track IP health, or handle retry logic for banned IPs. Every request is routed through a clean IP automatically, with geographic targeting available via the `country_code` parameter.

Proxy Pool
A managed collection of proxy IP addresses used to distribute outbound requests across multiple origins and stay below per-IP rate limits.
Residential Proxy
An IP address assigned by an ISP to a real residential device, used to route scraping requests through genuine consumer IPs.
Rate Limiting
