[arin-ppml] Draft Policy 2011-6: Returned IPv4 Addresses

So let's try this again. I have multiple version from AC discussions
and PPML discussions related to 131, 2009-3 which is formally
abandoned and not relevant to this discussion and...and... -- it
certainly is confusing as some have noted.

The RSA component is not currently part of the discussion. We need to
wait out the process to see what is going to transpire. I'm still
opposing the proposal since the language that was submitted was
changed before it was even placed on the docket and merging legacy
considerations with address space that is clearly controlled by ARIN
is likely to result in confusion.

I think that as long as it makes it to Puerto Rico it doesn't really
matter so it's probably worthwhile to wait it out untl then and stop
polluting Tony's mailbox. :)
