RBN <strong>study</strong> – before and after<br />
David Bizeul<br />
Some companies have already installed such filters. iDefense has asked its customers to filter RBN IP addresses [ 61 ].<br />
Some ISPs have begun to enforce such “bad network” filtering [ 62 ]. It may be a good start.<br />
Spamhaus is making a fantastic work by maintaining a DROP (Don’t Route Or Peer) list [ 63 ]. This list provides all the<br />
bad networks that companies or even ISPs can assuredly filter to build a safer world. As an example, most of RBN IP<br />
blocks have been listed in DROP. Spamhaus plans on distributing its DROP list in a BGP feed soon. This list should be<br />
used by every Tier-1 network on the Internet.<br />
Large ISP should also focus very closely on peering agreements. This could have avoided RBN from getting connected<br />
directly with main UK ISP.<br />
