Subnet diversity
The spread of a provider's addresses across distinct network blocks. Two pools of the same headline size can differ enormously in how many separate networks they touch.
Why it costs you money
Sites block by range, not by single address, so a pool concentrated in a handful of subnets can be neutralised in one move. This is why a pool-size claim on its own says very little, and why we label every pool figure as the vendor's own number rather than a measurement.
