On a different topic, section 5 covers IPv6-only issues.
I'm a bit concerned that this might need a health warning:
deploying NAT64/DNS64 might cause pain and suffering.
Perhaps after this text:

>    Together, RFCs
>    6146 and RFC 6147 provide a viable method for an IPv6-only client to
>    initiate communications to an IPv4-only server.

we should add something like:

   At enterprise level, operating NAT64 and DNS64 services for
   heavy usage may have significant practical implications.

Also, the last paragraph of section 5:

>    It is worth noting that for IPv6-only access networks that use
>    technologies such as NAT64, the more content providers (and
>    enterprises) that make their content available over IPv6, the less
>    the requirement to apply NAT64 to traffic leaving the access network.

A reference to RFC 6883 would fit nicely there.
