Well, section 4 of draft-ietf-dhc-anonymity-profile-07 says: The choice between the stateful and stateless scenarios depends on flag and prefix options published by the "Router Advertisement" messages of local routers, as specified in [RFC4861]. When these options enable stateless address configuration hosts using the anonymity profile SHOULD choose it over stateful address configuration, because stateless configuration requires fewer information disclosures than stateful configuration. That seems pretty close from what you want, at least as far as "stateful DHCPv6" is concerned. -- Christian Huitema
