What is IP pool size?

An IP pool size is the number of addresses a proxy vendor says it can draw from, and it decides how much traffic a single blocked address can absorb before the work is affected. These figures are vendor claims rather than measurements, so treat them as a starting point for comparison. Bright Data states 400M+ residential IPs, Crawlbase states 140M residential IPs plus 98M datacenter, Decodo states 125M+ IPs, DataImpulse states 90M+ and Geonode states 7.5M+ residential IPs active monthly. Pool size also interacts with rotation settings, since a large pool configured to reuse the same session is worth less than a smaller one with wide rotation.
