draft-ietf-v6ops-addcon-01.txt Changes Made Based on WG Feedback Document was adopted as a WG work item Editorial changes Added a note on ULA vs (legacy) site-local addresses mentioning potential impact during renumbering and transitioning between the two types of addresses The Provider Independent address space was not discussed.

draft-ietf-v6ops-addcon-01.txt Changes Made Based on WG Feedback (cont.) Added more detail on the structure of the Anycast address and usage considerations Embedded-RP section: Clarified text, mention that there are 15 possible addresses that can be used for Embedded RP (not for multicast in general) Using these addresses is not a ‘constraint’, i.e. you can use these addresses for non-RP devices, but you may regret it later, so just bear that in mind Noted that CGA addresses are indistinguishable and that similar considerations apply

draft-ietf-v6ops-addcon-01.txt Service Provider Considerations Case Study: Planning considerations are analyzed from the perspective of the various roles played by the SP:  LIR  ISP  Network Access Provider Planning considerations are analyzed from the perspective of the entity that is assigned address space:  SP infrastructure  Large SP Customers  Small SP Customers Observations
