I guess the larger picture is what are we trying to protect and what are trying to protect that from. -----Original Message----- From: owner-nanog () merit edu [mailto:owner-nanog () merit edu] 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 On the other hand, how much of a problem is obsolete bogon filters causing everytime IANA delegates another block to an RIR?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?
