What a load of rubbish. How is ARIN or any RIR/LIR supposed to know the intent of use? Push has come to shove and those that have incorrectly treated address assignment as immutable will need to correct their ways (excluding legacy assignments). This will be painful for some. Note we all could start using IPv6 and avoid this problem altogether. There is nothing stopping us using IPv6 especially for MTA's.
