At the risk of creating an matter-antimatter reaction within ARIN's list
server, I will use both Randy's and Milton's names in the same email. I
will apologize now if the chain reaction destroys the universe. :)
Randy Bush and others have the done some related work;
For paper and slides;
Quick summary from there data;
# tested default default-free mixed
stub 24,224 77.1% 19.3% 3.6%
small ISP 1,307 44.5% 42.2% 13.3%
large ISP 246 17.1% 60.6% 22.3%
You could probably come up with some kind of model to create an estimate
of how many routers that represents.
When I look at this data it seem to me that it supports the general
hypothesis those that add prefixes to the DFZ are probably not sharing
equally in the costs associated with the additional prefixes.
Whoops, there she Blow......
