The AHBL (Abusive Hosts Blocking List) is exclusively related to Email hosts that are having problems in their hosted network environment. Either they have had accounts that have been hijacked and used to send spam, or they have customers that are sending spam (unsolicited bulk mail) and as a result, large portions of their netblocks have been blacklisted.

Ahbl Reports Subnets

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