What changed
The proposal evolved from a PA-only certification model with maintenance tied to membership or contractual status in version 1, to explicit dependence on the registered resource record in version 2. Version 3 framed the service as RPKI and added a member-in-good-standing condition. Version 4 broadened initial eligibility to IPv4 resources marked "ALLOCATED PA" or "ALLOCATED UNSPECIFIED" and IPv6 resources marked "ALLOCATED-BY-RIR", while continuing to defer PI, ERX and legacy resources. Across the versions, certificate validity and continuity remained tied to registration status. The proposal was ultimately withdrawn on 2011-07-26, so these changes describe proposed policy text rather than an adopted policy.
