Hi Dusan,

    "3.  Definition of IPv6-only
    
       Consequently, considering the context described in the section above,
       if we want to be precise and avoid confusing others, we can not use	
       the terminology "IPv6-only" in a generic way, and we need to define
       what part of the network we are referring to.
    
       From that perspective, we define the "IPv6-only" status in a given
       part(s) of a network, depending on if there is actual native
       forwarding of IPv4, so IPv4 is not configured neither managed."
    
    The document defines IPv6-only not only for the network parts but also for a host/router.

-> I see this document as to have view "end-to-end". So, from host A (source) to host B (destination), is it IPv6-only? Under that perspective, the hosts, routers, involve in that end-to-end communication, are also part of the network. If this is not clear, I could expand the text on this section to clarify that. Do you have any suggested wording?
    
    "7.  IPv6-only WAN/access
    
       IPv6-only WAN or access can be used only if the WAN or access network
       isn't actually natively forwarding IPv4."
    
    Should use affirmative kind of definitions for IPv6-only, not only here but also in other sections. Instead of "isn't actually natively forwarding IPv4" should define what it IS forwarding, like "is natively forwarding IPv6".

-> I think it is clearer with the negative form, unless this is incorrect in English? I'm not native speaker. If I use affirmative it gets more complex:
"isn't actually natively forwarding IPv4"
vs
"is actually forwarding natively IPv6 and not natively IPv4"
    
    "10.  Transitional IPv6 host/router
    
       Transitional IPv6 host/router is a dual-stack host/router with
       IPv6-only WAN where IPv4 service support is provided by means of
       transition mechanism, IPv4aaS (IPv4-as-a-service)."

-> not sure what is the input here?
    
    Dusan
    
    Why is it important to mention WAN address family? Why WAN must be IPv6-only?

-> Because the full reason or "starting-point" of the document is the IPv6-only terminology clarification.
