Spamhaus BGP feed (BGPf)

Spamhaus offers a Border Gateway Protocol feed of three of its lists, which Spamhaus refers to as the BGPf, which is comprised of the following three datasets: the Botnet C&C list (called BGPCC when served via BGPf), the DROP list, and the extended DROP list (EDROP). These lists are intended to be loaded into routers and then used to block packets originating from IPs involved in certain types of malicious activity. Following is further information about BGPf:

Each of the three lists have their own listing policies. Those listing policies are public, and can be found here:
