Mark,<div><br></div><div>At no point did I suggest that anyone turn off IPv4 - probably ever. If you think that, then you sadly misunderstood my email. We will be living in a dual stack world for a long time before people put a bullet in ipv4.</div>

Really? In which decade do you think that <a href="http://facebook.com" target="_blank">facebook.com</a>, <a href="http://yahoo.com" target="_blank">yahoo.com</a>,<br>
<a href="http://twitter.com" target="_blank">twitter.com</a> and <a href="http://google.com" target="_blank">google.com</a> will stop returning an A RR? And what is<br>
their incentive for doing so?<br>
<br>
You need to explain why a business would voluntarily stop listening to<br>
IPv4 traffic and why ISPs would stop carrying it.<br>
<br>
If you have no explanation for that, then what has any ISP got to lose<br>
by just carrying IPv4? After all, it gets to everywhere and probably<br>
will do so for a very long time into the future.<br>
<br>
The big problem is that turning off IPv4 has no value-add and turning<br>
on IPv6 has no value-add, so no one cares to do either. Ergo,<br>
IPv4-only systems will continue to work for the foreseeable<br>
future. That means there is zero imperative to support IPv6.<br>
<br>
I'll be proved wrong when any major website discards their A RR web<br>
site and only advertise an AAAA web-site. Any volunteers? Apnic? Arin?<br>
ICANN? <a href="http://eintellego.net" target="_blank">eintellego.net</a>? Jut curious. If IPv6 is such a hit, when do you<br>
guys plan to drop your IPv4 RR?<br>
<br>
