<div>Respectfully, Robert - you have not
addressed Don's question. You've made an excellent case for what
<i>not</i> to do (and i wholeheartedly agree), but nothing on the
side of the case for what to <i>do</i>.<br>
<br>
I'd really be interested in hearing the group's take on the actual
benefits of IPv6 <i>now</i>. The only one i can think of is:<br>
<ul>
<li>reduced network complexity and support costs due to the
elimination of NAT</li>
</ul>
<p>I expect that this benefit would be eliminated many times over
by the cost of:<br>
</p>
<ul>
<li>implementing IPv6 operationally on the network<br>
</li>
<li>retraining staff (I can't even get the help desk folks to
stop using IPv4 addresses when DNS is already set up and
working!)<br>
</li>
<li>re-implementing firewalls to eliminate NAT</li>
<li>(for small multi-homed organisations):</li>
<ul>
<li>applying for provider-independent address space</li>
<li>implementing BGP (including acquiring the hardware and
skills/partners to roll it out)<br>
</li>
</ul>
</ul>
All the other benefits of IPv6 that i can think of are future:<br>
<ul>
<li>ability to grow the network beyond the present limits
imposed by IPv4 addressing</li>
<li>not being subject to the increased cost of acquiring more
than a /22 of IPv4 address space</li>
<li>competitive advantage over competitors who have neglected to
plan for the future<br>
</li>
<li>not being subject to the exhaustion of IPv4<br>
</li>
<li>not being cut off from customers who have already fallen
victim to the exhaustion and are IPv6 only</li>
</ul>
<p>It would be a foolish manager who ignored that big list of
future benefits (especially the last two), but i can very much
understand him or her continuing to defer it until next year's
budget, or at least pushing the project down the priority queue
until bitten.<br>
</p>
IPv6 is a technical <i>must </i><i>do</i>,<i> </i>and i
continue to be wracked with professional guilt that i didn't start
sooner, invest more learning time, and build up more practical
experience with it, but i haven't managed to find a silver bullet
for convincing management. Some of the best Internet minds in the
Asia-Pacific region are on this list. If they can't come up with
some good sells for the benefits of IPv6 now, what hope does the
average IP professional have?<br>

<div><br></div><div>Other benefits that I'm aware of:</div><div><br></div><div>* Natively integrated autoconfigure - lowers cost of management.</div><div>* Integrated IPSEC - tighter native security.</div><div><br></div>
