While I'm behind some of the inventory projects (so you can go ahead and =
fix.. let me know
if you need/want the URLs to see data for your networks)...

I must provide credit to those behind the "Amplification Hell" talk at =
NDSS.  If you
are at all interested in what is going on, you should attend or review =
the content.

BCP-38 on your customers is going to be critical to prevent the abuse =
reaching your
network.  Please ask your vendors for it, and ask for your providers to =
filter your
network to prevent you originating this abuse.

If you operate hosted VMs, servers, etc.. please make sure those =
netblocks are
secured as well.

You can easily check your network (As can the bad guys!) here:
