# Proxy Pool

A managed collection of proxy IP addresses used to distribute outbound requests across multiple origins and stay below per-IP rate limits.

A proxy pool is a managed inventory of proxy IP addresses that a scraping system draws from to distribute outbound traffic across many origins. The pool manager assigns IPs to requests, tracks IP health (response rate, ban status, latency), rotates out degraded IPs, and sources replacements to maintain a target pool size.

Proxy pool management requires solving several operational challenges: IP sourcing (provider contracts, ethical residential networks), health monitoring (continuous probing of each IP against target sites), geographic distribution (IPs in regions where the target site serves content), rotation strategy (per-request, per-session, or time-based), and cost optimisation (using cheap datacenter IPs where possible and expensive residential IPs only when needed).

Self-managed proxy pools typically require dedicated infrastructure and ongoing operational overhead. AlterLab maintains its own proxy pool infrastructure, automatically selecting the appropriate proxy type and geographic location for each request. Developers submit URLs and receive responses — all proxy management is handled transparently.
