Umm.. don't bother. Let's think this through. 2Mbits/sec of bandwidth
will only sustain about 40 56KB modems doing a simultaneous download.
Even adding in think time and the like, a /24 should be plenty wide enough.
The *BIG* question is how the ISP intends to make any money at that scale.
Figuring even a 10X overcommitment, that's 400 customers at $20/mo or so,
for an inbound cash flow of only $8K/month, with which they get to pay their
bandwidth charge, their tech support, and everything else.
I wish them luck.
