I've tried it before and found that apart from some broken
implementations, the biggest issue seemed to be certain Internet
banking sites that seemed to view traffic from addresses ending in .0
or .255 as invalid.

Discussions with the banks in questions were not that fruitful, so we
just treat each assignment as a /24 and leave out the .0 and .255
addresses.
