While the issue on the surface appears to be fairly pety, the
223/8 block was assigned to a RIR. 223.255.255/24 is reserved per rfc.
And this is why my question. RFC 3330 states that 223.255.255/24 can be
assigned to a RIR. What gives one RFC weight over another? Is it an
issue of RFC type or obsoletion status?
