<div dir="ltr"><div><div><div>Hi Chris,<br></div>In my personal opinion....<br><br></div>You make alot of good points about Ipv6,especially about the backward compatibility but there is no much point talking about it now - that bus has already passed.<br><br></div><div>Everyone's networks are different so we are all going to have different way to approach Ipv6 - For some this will be CGNAT, for some this will be native IPv6, some this will 6rd, some this will be <span class="">464SLAT, and some will stick their heads in the sand.</span><br><br></div><div>The main aim of everybody is happy 'paying' users with happy eyeballs and growing customers.<br></div><div>I know my in-laws use Ipv6 on NBN without even knowing or caring - They just care they can get to google/facebook which are 100% Ipv6 traffic.<br><br></div><div>The realistic options are Ipv6 deployment in some form or another. That's it.<br><br></div><div>This doesn't have to be a massive project with hundreds of people done in 1 month - It's a process not a leap.<br></div><div>Ipv4 is not going to be turned off tomorrow as Noel highlighted.<br></div><div><br></div><div>For starters, audit your devices - do they support Ipv6 now or need an upgrade. Flag it for next software upgrade if needed.<br></div><div>The next step - Speak to your upstream and get a Ipv6 bgp peering happening.<br></div><div>Next speak to your provider to get an allocation, or speak to apnic to get a ipv6 allocation.<br></div><div>Start working your way out from your edge/core devices to enable Ipv6 and establish a deployment plan.<br></div><div>Mandate that any new service should be Ipv6 enabled where possible as well to save going backwards.<br></div><div>At this point - you are well on the way to a Ipv6 deployment with minimal OPEX/CAPEX investment.<br></div><div>Trust me, Everyone is going to have problems with a ipv6 deployment with varying degrees of difficulty but that's what vendor support is for and ausnog to see if anyone else has found a way to get that square peg in that round hole ;)<br></div><div><br></div><div>Next, Look at getting <a href="http://minopher.net.au">http://minopher.net.au</a> enabled for Ipv6. ;)<br></div><div><br></div><div>The Ipv6 preparation and audit work will ensure that when the time does come for Ipv6 only websites, consumers/companies are not complaining - Why can't I access this porn website/service, and they are not changing providers because you can't fix it in a couple of days as your CGNAT solution ran out of IPs need a total ipv6 deployment.<br><br></div><div>Also with NBN - It's the perfect business case opportunity in a company to establish that any NBN connections should be fully dual-stacked.<br></div><div><br></div><div><br><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 26, 2015 at 11:13 PM, Chris Hurley <span dir="ltr"><<a href="mailto:chris@minopher.net.au" target="_blank">chris@minopher.net.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;color:rgb(0,0,0);font-size:12px;font-family:Calibri,sans-serif"><div><div><div>I could be wrong (and I have been before ;-), but the biggest mistake in IP6 was not making it backward compatible with IP4.

Blaming a lack of IPv6 deployment progress on “IPv4 not being broken yet” is self-defeating, it’s the same as saying “my water pipes still work even though they have a few big cracks leaking, why should the council replace them until the water completely stops flowing?” or “nobody else bothers to put rubbish in a bin, so I won’t either, plus I invented this new thing to add onto my shoes to make me higher to keep out of all the litter on the ground, everybody else needs to buy some now too”<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif">Unfortunately CGNAT is now a requirement for a lot of companies, due in large part to a lack of progress on IPv6, but it doesn’t go both ways.

Again as has been said, there is very little commercial incentive to do this, but it’s really going to be minimal capex to implement with very little additional opex spending so it shouldn’t be as big a cost issue as it may seem, at least for basic connectivity for servers etc.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif">Obviously we can’t argue “don’t do CGNAT” now, we are well past that, but I would say that anybody looking at or doing CGNAT should at least have an IPv6 deployment plan they are actively progressing, even if it’s slowly.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif">The problem with IPv4 is that we can continue to do CGNAT theoretically indefinitely, though the logging required will continue to increase and the port ranges that are allowed for per user will continue to shrink until it becomes practically untenable. The issue is in the meantime we are stifling innovation and strangling available uses for the internet. In the next few years we will see a continued explosion of devices that will need IPv6 to be able to truly be used to their full potential, but a lot of those will just continue to not work or be underutilised until the network under them has the capacity to handle them gracefully.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;color:rgb(31,73,125);font-family:Calibri,sans-serif">On the topic of IPv6 only hosts, I have heard there are ISP’s in China and Europe that are doing this but I have nothing concrete, anybody know if that’s fact or not / have a link?
