IPs massive blockade

Hello:

Until now I was using a program called PeerBlock blocking “malicious IPs” of Bluetack list, etc. The problem is that it has dropped support for this program, and I would like to know how to add massive lists of IPs to filter, ie to prevent connecting with me (both incoming and outgoing), without having to manually add IP to IP.

The IP filter of CIS is not suited to handle those type of big lists.
