Proxy pool
A proxy pool is the set of addresses a provider can route you through. 30 of the 42 providers Proxy Compare tracks publish a size, read 5 Oct 2026, the largest claiming 175 million. Every figure is the vendor's own claim, labelled that way, because nothing outside the provider can verify it.
Why it costs you money
Treat the number as marketing rather than measurement. It generally counts every address seen over an unstated window, not addresses available now, so a device online for ten minutes last March counts the same as one online today. We publish these as the vendor's own claim, labelled that way, because nobody outside the provider can check them.

Questions
How big is the largest pool on this site?
175 million addresses claimed, and 30 of the 42 providers publish a size at all, read 5 Oct 2026. Every figure is the provider's own claim and is labelled that way on the page.
Can the number be verified?
Not from outside. Nothing a buyer can run counts the addresses in somebody else's pool, which is why this site records the claim and the date it was read rather than presenting it as a measurement.
Does a bigger pool mean fewer blocks?
Only if it is spread out. Ten million addresses concentrated in a few ranges behave like far fewer to a target that blocks by range, and no provider here publishes that spread.
