Hi David,<br>
<br>
Did you intend for #1 to allow employing the 4.10 IPv4 space at<br>
locations outside the ARIN region if ARIN-allocated IPv6 addresses are<br>
being used there? So that as long as the IPv6 addresses are from ARIN<br>
they can get 4.10 space for as many GLOBAL locations as a registrant<br>
wants?<br>
<br>
To the best of my understanding, ARIN doesn't have much in the way of<br>
proscriptions against using ARIN IPv6 allocations outside the region.<br>
>From what I read in section 9, they basically have to have a legal<br>
existence in the ARIN region and deploy at least a /44 there.<br>
<br>
