Note that 224.0.0.0/3 already includes 255.255.255.255/32. Specifically, it encompasses the Class D (multicast) addresses 224.0.0.0/4, the all-ones broadcast address 255.255.255.255, and the unused Class E (experimental) space that lies between. Also, I was under the impression that for historical classful reasons all of 0.0.0.0/8 is invalid and should be dropped. What's 204.152.64.0/23 ? -roy
