What changed
Proposal 2011-03, “Post-depletion IPv4 address recycling,” was introduced on 20 May 2011 and accepted on 30 October 2011. Its version 1.0 proposed adding rules to section 5.6 for returned IPv4 space that RIPE NCC would retain and reissue rather than return to IANA: apply the last-/8 rules, update minimum allocation sizes if necessary, and use multiple allocations totaling no more than a /22 when a single /22 could no longer be made. The proposal said the existing final-/8 rules would remain unchanged.
