David -
  Thank you for asking that, as it caused me to go find the 
  reference and reread it.  My summary from memory was quite
  weak (e.g. legacy /8 blocks are maintain per the RIR policies
  but when returned will go to the IANA via the RIR), so it is 
  better to read the original on the IANA web site:


Hope this helps,
