But! Seldom I am experiencing some problems with that kind of addresses. There is a number misconfigured "antihackers" filters on the Net blocks .0 and .255 as they thinks it is always broadcasts. A bit soul-save discussion with such admins usually fixes the problem ;)
Unfortunately this is not the experience I have from the field. We're using superneted /20 blocks composed out of `class c'-ranges for cable-tv broadband customers. I had to change the DHCP-server to prevent the assignment of .0 and .255 since we've got a lot of problems with such misconfigured filters in the net and we didn't have the time for all those 'soul-save' discussions with admins not understanding the concept of classless ip-routing.
