<html><head></head><body>Hi Sylvain, Maybe the definition must be taken a little different: conversion for own use. The reason is that some PI-Owner became LIR, e.g. because the size of their business grew, that it became reasonable. Earlier it didn't make sense for me to become LIR as two /24 were sufficient. With an eye on the "Last /8 Policy", your proposal would mean, these LIRs would have to return their space without having a chance to get new pa to satisfy their current need. Anyway, even if I'd return a /22 and receive another PA (my "last /22") this wouldn't give more aggregation. The only thing that changes, would be a huge amount of work for me... or (if not converting my PI to PA I have to pay 50 EUR more than e.g. Deutsche Telekom which holds many many more IPv4 than me, only that because my initial assignment has the label PI...

Allow LIRs to change the status of their PI assignments to PA allocations (if equal or larger than the minimum allocation size)</blockquote> I do not support this since blindly allowing LIRs to change PI to PA would lead to very permissive reuse of space that was assigned in an exception mode to the aggregation principle for very specific reasons. So I consider if the purpose of this assignment is no valid anymore then it should be returned to free pool in the general case, not reused for whatever else. This is enforced by the ability for LIRs to transfer (I mean, to sell) PA space. Obviously converting PI to PA and sell it would be the right choice for anybody having unused PI subnets today. I know convervation looks like an old fashioned and void policy for many LIRs today, however free IPv4 still is a rare public ressource needed by many to survive. So available IPs should be returned to RIR. Best regards, Sylvain fr.opdop !DSPAM:637,520763c7296831255961281! </pre></blockquote></div></body></html>
