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.
