Automatic Bogon Updates

As most of you are security minded people out there, you already know what Bogons are. If not, here is what wikipedia has to say about it. It’s basically addressing that no packets should be addressed from.

Steve-o clued me into the Team Cymru bogon project. In a nutshell what they do is setup a BGP peer with you and send you the updated bogon list with a community string attached. You can then in your router setup a script or route-map to blackhole all traffic sourced from these addresses. Best part is that when they update the list on their routers, it updates automatically on your infrastructure. Did I mention that it’s free?

This being a free service and all, I would say use it at your own risk. I know it would make for a good April fools day joke to blackhole google 😛
