Dear Colleagues, During the Address Policy Working Group session at the RIPE 53 Meeting in 2006, the community supported the idea of having an impact analysis conducted by the RIPE NCC for each policy that has been proposed. The community wanted to know the expected impact that a policy may have if it is eventually accepted. The RIPE NCC will therefore conduct an impact analysis for every policy proposal that moves to the Review Phase of the RIPE Policy Development Process (PDP) from now on. The impact analysis provides projections in the two areas most discussed by the community: A. Impact of the policy on the registry and addressing system - Information will be provided about the possible impact of the proposal on address/Internet number resource consumption and fragmentation/aggregation. B. Impact of the policy on RIPE NCC operations/services The first impact analysis has been created for the proposal 2007-04, IANA Policy for Allocation of ASN Blocks to RIRs. You can view this analysis under 'Additional Information' in this proposal at: http://www.ripe.net/ripe/policies/proposals/2007-04.html Kind regards Filiz Yilmaz RIPE NCC Policy Development Officer
