Rich & I managed to get draft-ietf-ipngwg-addrconf-privacy-xx.txt revised before the cutoff. The main changes are to address the issues raised in Rich's mail to the ipng list on 6/6/2000. Specifically: 1) When a site has multiple active prefixes (e.g., is multihomed) it generates an anonymous address for each of those prefixes from the same random interface identifier. This reduces the number of solicited-node multicast addresses a node must join. 2) Public addresses are not deprecated as in -01. Instead, draft-ietf-ipngwg-default-addr-select-xx.txt was updated (and is in the publication queue) to give precedence to anonymous addresses. Note that this places a normative dependency from this document to default-addr-select. One advantage of this change is that the set of public addresses (and their associated liftimes) will be the same whether or not anonymous addresses are in use. Previously, the public address was deprecated (preferred lifetime set to 0) in order to ensure that it was not selected for outgoing communication. 3) Additional rules have been specified to ensure that when RAs update the lifetime of public addresses, the corresponding lifetimes of associated anonymous addresses are also updated. RAs can only shorten the lifetimes of anonymous addresses, not lengthen them. In the previous version of this draft, the lifetimes of anonymous addresses were not properly adjusted downward in some circumstances.
