I guess the larger picture is what are we trying to protect and what are trying to protect that from. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Sean Donelan Sent: Friday, March 02, 2007 3:19 PM To: Roland Dobbins Cc: NANOG Subject: Re: Where are static bogon filters appropriate? was: 96.2.0.0/16 Bogons On Fri, 2 Mar 2007, Roland Dobbins wrote: >> Sometimes, network operators have to take the bull >> by the horns and develop their own systems to do a job that vendors >> simply don't understand. > > Concur - but it seems that many seem to be looking for someone else to > do > this for them (or, perhaps, the lack of someone to do it for them as an > excuse to do nothing at all). How much of a problem is traffic from unallocated addresses? Backbone operators probably have NetFlow data which they could mine to find out. On the other hand, how much of a problem is obsolete bogon filters causing everytime IANA delegates another block to an RIR? Or by the way, how much spoofed traffic uses allocated addresses?
