I'm aware of the construction of a CIDR prefix, I meant what are you using to categorise IPs from requests to look up mask size? whois? using published NIC/RIR data? what's in BGP/routedumps? other?
late but i believe they mean they check for every possible range, e.g. if it's only 1.2.3.5 making noise it'll get banned as a /32 but if 1.2.3.6 is too it might justify a /30
