I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. This is an informational draft that provides guidance for deploying IPv6 addresses. The security considerations section does exist and states that the draft does not change the security properties of the different models outlined in the draft. Reading the individual model RFCs provides sufficient information for the possible security implications. General comments: None. Editorial comments: s/connectivity not available/connectivity is not available/ s/and are have/and have/ s/IPv6 networks, notably NRENS like Internet II/IPv6 networks; notably NRENS, Internet II/ Expand NRENS. s/easy with to/easy to/ s/establishment native connectivity is not possible/native connectivity can not be established/ s/more like to/more likely to/ Shawn. --
