So, a number of events have transpired recently culminating in my
attending this week's MAAWG (Messaging Anti-Abuse Working Group) meeting
in San Francisco.  Short ride and low fees helped.

I've been talking to a number of folks in that community about some
ideas I've previously discussed here, got around to presenting some of
them in the form of a paper, presented to fairly positive interest at
the meeting.  The basic concept is to use publicly available BGP router
data to identify ASNs and CIDRs from IPs through a DNS query.

The paper, "CIDR House-Rules:  Use of BGP router data to identify and
address sources of Internet abuse", is available at:


Current plan is to extend that in some follow-up papers.  Among other
things, it looks as if the sort of data gathering + enforcement split I
discuss would be pretty doable with stock Cisco gear via QoS or similar

... oh, and, ObLyxRocks.  Very largely painless authoring here,
significantly less than several of the alternatives.  Several
alternatives failed to meet or exceed expectations (or needs).
