Every /24 inside it
00 · Evaluate
Test the real build first.
An evaluation license puts a full current build in your hands, with no sampling, so you can measure it against your own traffic before anyone talks about terms.
01 · License
Then license what you use.
Standard, for detection and decisions inside your own product and operations.
Redistribution, when the data ships onward inside what you sell, priced by scope rather than by seat.
Annual terms, a named contact, and monthly, quarterly or yearly payment.
