I've seen this too.  Dialup boxes that use dynamic pools prefer them to
start on a subnet boundry so that they can announce a single aggregate
route for the whole pool. However we ran into problems with using x.x.x.0
before (think it was a broken TCP/IP from some vendor or another) and so 
we moved the dynamic pools further up the subnet.
