font-family:"Arial","sans-serif"">The current terminology in section 4.10 is vague and could allow a<br>
variety of interpretations which could lead to allocations or<br>
assignments being made to ISPs intending to misuse the space for general<br>
deployment by using IPv6 overlay technologies as a "IPv6 deployments"<br>
requiring IPv4 space for transition. For example, the current policy<br>
could be interpreted to enable an ISP to require IPv4 addresses for all<br>
IPv6 customers to roll IPv6 out as 6rd to customers who would be<br>
otherwise unable to get IPv4 space. This is clearly outside of the<br>
original intent of the proposal which created 4.10 (6rd was not yet<br>
envisioned at the time that was written). This proposal seeks to clarify<br>
that intent and tighten up the requirements for organizations seeking to<br>
get space from this limited final resource so that it truly is available<br>
to facilitate transitional technologies.</span><o:p></o:p></p>
