As others have pointed out, that's actually perfectly legal. However some operators have (had?) "classful" firewall rules that prohibit packets that come from IP addresses that would have been considered a broadcast address in a pre-CIDR world. This very problem bit me on the backside back in about 2001 when I had to update the RADIUS server I had written to prevent it from issuing .0 and .255 because my DSL customers getting assigned those addresses couldn't reach Microsoft's website.
