</div>But do we want to state that? �In web hosting environments, it's not<br>
uncommon to have 100 different customers on the very same hardware, each<br>
of them using a different IP(v6) address - and with vserver/jail type<br>
setups, each of them is typically only using a single address (unlike VM<br>
style setups where you might want to use "more").<br>
<br>
Do we mandate (or even "encourage") using 100 different /64s for that<br>
purpose? �I'd say "no" :-) - let the ISP do that if they *want*, but<br>
do not *mandate* it.<br></blockquote></div><br></div><div class="gmail_extra">I think that was a nice way of rephrasing part of my point, thanks Gert!<br><br></div><div class="gmail_extra">Another point is that these kinds of "customers" are far more ephemeral than what I believe RIPE policy is meant to regulate.<br>

<br></div><div class="gmail_extra"><a href="http://www.ipv6.oyet.no">www.ipv6.oyet.no</a> could have a different IPv6 address, but still be the same "customer".<br><br></div><div class="gmail_extra">But the IPv6 address used by <a href="http://www.ipv6.oyet.no">www.ipv6.oyet.no</a> could also be serving <a href="http://www.ipv6.onepocket.no">www.ipv6.onepocket.no</a>, a different "customer".<br>
</div><div class="gmail_extra"><br><br>And in either case, the IPv6 address used for this purpose may not really be _assigned_ as such, but rather used temporarily, until the website(s) in question is moved to a different server or virtual server with different routing, or merely different address space segmentation.<br>
<br></div><div class="gmail_extra">I imagine that e.g. Amazon or similar large-scale operations would be unhappy having to segment their space in the manner I understood the proposal at first.<br><br><br></div><div class="gmail_extra">
If the horse ain't dead yet, I'm happy to flog it a bit more by going into practical, human-readable IPv6 address segmentation for keeping address manageable. ;)<br></div><div class="gmail_extra">-- <br>Jan
