But I think people were expecting something from the IAB/IETF before IANA actually allocated previous special use reserved address blocks. My understanding was RFC3330 was written by IANA and published by IANA to document existing practices, not to change previous practices. Eventually we'll use it. The simpliest solution is for IANA to inform APNIC that it was an oversight. The 223.255.255.0/24 network block within the 223/8 CIDR block assigned to APNIC is still IANA-RESERVED per RFC3330 and previous practice; and not allocated for APNIC's use at this time. Its probably easier for APNIC to flag the 223.255.255.0/24 network within the CIDR block 223/8 as IANA-RESERVED in the APNIC database just like ARIN does with the other IANA-RESERVED blocks in ARIN's database; rather than do the ugly CIDR block breaking of 223.0.0.0-223.255.254.255 and 223.255.255.0-223-255.255.255. But that is a decision for APNIC.
