As far as I know .0 and .255 are network and broadcast addresses respectively, NEVER should a workstation be configured on these addresses, unless something drastically changed in the RFC's for IPv4 which I am not aware of...
only on a /24. on /0 - /23 only the first .0 is network, and the last .255 broadcast. on /25-/30 it depends on where the network begins and ends. /31 has no directed broadcast. /32 is a single host and similarly has no directed broadcast.
I for one am filtering .0 and .255 at my border routers, and also rate limiting echo at a reasonable rate... and have never gotten a complaint about people not being able to reach or be reached...
