That is not a valid subnet mask. The error message tells you exactly the problem with it.

@n8te honestly that error message is awful. It assumes that the user knows how to convert a dotted-decimal subnet mask into binary, and that the user knows how to interpret such a message. A normal person would say "Uhh none of my bits are set to 1, they are set to 2, 5 and 5"

Under normal circumstances, 255.255.255.255 (/32) is not a valid subnet mask. There are situations where that is a valid subnet mask, which is when you have a peer to peer link on a platform that supports that subnet mask (think ADSL on a router. You can also configure ethernet links with a /32 in Linux with certain networking flags, but requires you to run a routing daemon to get any traffic anywhere).
The minimum subnet size for a normal or older device is /31 (255.255.255.254)
