A year or so ago my experience was that Windows Server 2003 is not able to connect to a device with a .255 address from what was a once classified as a C network. A Linux box had no issues with the same. I would say there are still a few TCP/P stacks out there that don't fully support classless networks. Ivan Alastair Johnson wrote:

Curiousity about what people are using as far as addressing pools these days - lots of /24s (and excluding the end addresses), or bigger blocks?
More specifically, is anyone handing out the .0 and .255 addresses, or are there still sufficient CPE/endpoints out there which cope poorly with those addresses?
I tend to use larger subnets, but exclude .0 and .255 (lots of BRAS-y type equipment can do this; or intelligent DHCP/RADIUS servers). I found there was still too much broken equipment and OS, or broken firewall admins, on the internet.
I noted Vodafone handing out .0 IPs on their 3G service a few months ago, and it did indeed cause some things to break for me.
