Re: .255 and .0 addresses

* Jon Lawrence:

Without doubt, the pools must be bigger than /24 in order for .0 or .255 to be used as host addresses. Never tried it personally, but I can see no reason why .0.255 or .1.0 wouldn't be usable in a .0.0/23 - obviously assuming that you pass /23 to the hosts as a netmask.

Some sites filter .0 and .255, but I don't see why one should support such misconfiguration. ISPs with large dial-up ranges certainly assign .0 and .255 addresses to customers.
