<div><font size="2" face="Arial">Getting into more general terms I think we all need to acknowledge that for 99.99% of our customers, there is nothing in V6 for them. For the industry, it's all about keeping the lights on in world depleted of V4 address space.</font></div>

<div>If they get a static subnet then do they get to play with reverse mappings?</div><div>How will the transition from v4 to dual stack to some interim step to v6 only go?</div><div><br></div><div>I know a lot of the geeks will go "well, obviously a static /48 with our own controllable reverse mappings" but on a LARGE scale with mostly non-geek home users then what exactly does it look like?</div>
