I just skimmed draft-ietf-ipv6-rfc2462bis-07.txt, the current draft for
IPv6 autoconfig. I saw nothing in it that prohibits its use on
multi-interface hosts. In fact, there are several places that
explicitly use the plural form, such as the abstract:
This document specifies the steps a host takes in deciding how to
autoconfigure its interfaces in IP version 6.
The document is in Last Call for promotion to Draft Standard; if I'm
wrong and there is such text in there, send a note to firstname.lastname@example.org and/
or email@example.com complaining. The deadline is 28 January 2005.
