Actually, that's often not the case.  Through NAT and other modern
marvels, it's possible to have massively overpopulated netblocks that
all respond.  The largest amplifier we've found yet was 170,000x (on

Thank you Troy, However my point remains.


Roeland,

I believe that during the last run, netscan tested down to the /27
boundry.  While I agree that this isn't as complete as testing down to the
/30 boundry, even testing to the /24 boundry provides more information
than not testing at all.

Additionally, the website indicates that there will be another test down
to the /27 boundry.
