  2. OVERVIEW • Document <draft-ietf-ipv6-addr-arch-v4-00.txt> Diffed version: http//people.nokia.net/~hinden/draft-ietf-ipv6-addr-arch-v4-00.html • Draft has changes in two areas: • Deprecated the Site-Local prefix • Resolve issues raised in IAB response to Robert Elz appeal

  3. DEPRECATE SITE LOCAL • Major Changes: • Removed Site-Local from special list of prefixes in section 2.4. • Split section titled "Local-use IPv6 Unicast Addresses" into two sections • “Link-Local IPv6 Unicast Addresses” • “Site-Local IPv6 Unicast Addresses” • Added text to new section describing Site-Local deprecation. • Added instructions in IANA Considerations to reserve and not reassign the site-local prefix. • Changes are dependent on approval of Site-Local Deprecation draft

  4. IAB RECOMMENDATIONS • Changes: • Added clarification to section 2.5 that nodes should make no assumptions about the structure of an IPv6 address • Changed the text in section 2.5.1 and Appendix A to refer to the modified EUI-64 format interface identifiers with the "u” bit set to one (1) as “universal”. • Added clarification to section 2.5.1 that IPv6 nodes are no required to validate that interface identifiers created in modified EUI-64 format with the "u" bit set to one are unique.

  5. MISCELLANEOUS • Changed the reference indicated in section 2.5.4 "Global Unicast Addresses" to RFC3587.
