I realize that technically they are valid addresses, but does anyone assign a node or server which is a member of a /22 with a x.x.x.0 and x.x.x.255? Is it just a manner of preference on whether or not to use them, or are there functional reasons you shouldn't; either with rfc 1918 addresses or public addresses. I like to use them for critical service machines, since many versions of Windows will not send packets to them, so they are protected from most (but not all!) botnets. -- TTFN, patrick
