What is Proxy Pool?
The total set of IP addresses a provider can assign. A larger, more diverse pool means lower detection rates and better success at scale.
Pool size is the headline number every provider advertises, but the useful question is narrower: how many usable IPs exist in the specific country, city or network you actually need. A pool of tens of millions is no help if only a few hundred sit in your target market.
Diversity matters as much as volume. A pool spread across many autonomous systems and subnets is far harder to filter than one concentrated in a handful of ranges, because blocking a whole subnet is cheap for a defender and blocking thousands of unrelated networks is not.
Freshness is the third factor. Addresses that have already been burned on a target stay burned, so a pool that is constantly cycling in new IPs holds its success rate while a static one decays.
