This blacklist generally adds /24 or /16 catch-all entries when repeated spam comes from a /24 or /16 and they do not foresee any legitimate email coming from these hosts.

Schulte Repors Subnets

Subnet-based Blacklists are used to reject email from entire rangues of IP Addresses, i.e. providers that are hosting companies sending spam, as well as single IP Addresses that may fall in that rangue of IP Address.
