If a customer is on IPv4 today, and it works, short of any
other issues, they won't be looking to move.<br></blockquote><div><br>+1 <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

If an Internet resource is only on IPv6, and the customer's
existing ISP only supports IPv4, the customer will
experience connectivity issues and will, invariably, start
shopping around unless their existing provider turns up
IPv6.<br></blockquote><div><br></div><div>+1 but realistically speaking is there anything like v6 only resource at the moment?<br></div></div></div></div></blockquote><div><br></div><a href="http://thegoodlife.delong.com">http://thegoodlife.delong.com</a></div><div><br></div><div>I really need to put some more meaningful content there, but it's a start.</div><div><br><blockquote type="cite"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div> <br></div><blockquote class="gmail_quote" style="margin: 0px 0px 0px 0.8ex; border-left-width: 1px; border-left-color: rgb(204, 204, 204); border-left-style: solid; padding-left: 1ex; position: static; z-index: auto;">

If new Internet users are signing up to an ISP that is
operating in an era where there is no longer any IPv4, the
customer still doesn't care what protocol his services are
running over provided there is end-to-end connectivity.
Again, the customer's ISP (or their competition), will need
to provide a solution to the customer that satisfies their
connectivity needs (be they native to IPv6 resources, or
translated to IPv4-only resources).<br>
<br>
Ultimately, the customer will go to where they can get<br>
service. That's the bottom line.<br></blockquote><div><br></div><div>Sure...this is a final future scenario. Just that at the moment we have few v6 champions.
