<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">We also need to start being a little more honest with people about what is involved in getting to V6. For far too long I have heard
V6 touted as some utopia, and I am as guilty as everyone else of this, saying that rolling it out isn’t a problem etc.</span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">The reality is, people need to know what they are going into, they need to understand the challenges, the pitfalls, and the advantages.
If you give them an unrealistic picture of what is involved, the moment they hit a challenge they weren’t expecting, they will shy away and convincing them to try again won’t happen.</span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">Until we openly acknowledge that rolling out V6 on a wide scale is a tough exercise, while at the same time being a necessity, we will
continue to struggle with adoption. We need to acknowledge both the benefits and the problems, so that the problems can be rectified. We need to start pushing back on vendors who are delivering sub-standard v6 compliance and we can’t do that if we don’t
talk about the issues.</span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">And talking about v4 fallback is important – because that alone can cause some… interesting challenges.
</span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">Let me give you an example – I had a situation last week where I was struggling to figure out, why the v6 traffic levels were so low.
I looked and I looked, and everything *<b>seemed</b>* to be ok – so eventually, I turned off IPv4 ENTIRELY on my test machine. Suddenly I discovered that all was not so well… what had been happening was that the system was using happy eyeballs and spotting
breakage and instantly doing IPv4 fallback.</span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">Once I disabled v4 entirely, I could clearly see the issue, and I logged tickets with the relevant content provider to get these issues
fixed. The initial reaction from that content provider was interesting – they disabled my ability to get quad-a records rather than fix the problem. At that point thanks to a very kind individual who contacted me after I put some posts on certain lists,
and a further escalation, they actually resolved the issue and I’m back to getting quad-a records and v6 traffic.
</span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;"> </span></div>
<div class="yiv4933295456MsoNormal"><span style="font-size:11.0pt;">Simply put, this is not an easy path we are on, it’s a path that has to be taken and we have no choice but to go down it, but let us
start talking openly about just how difficult that path can be, so that we’re prepared to actually face the challenges. Let us not start saying that people should simply “not concentrate on v4”, because that is not realistic. In all we do, we have to be
realistic and continue to put the customers first – and so as we move to v6, we have to keep THAT in mind as well.</span></div>

Again, I agree, though I also think that providing a plan needs to have more than that just a plan, there needs to actually be action on this plan as well (even with it being a difficult thing to do).<br clear="none">
<br clear="none">
It concerns me that we are at the point where we are, yet right now, for all the talk, I see very little actual deployment of v6 beyond core networks.<br clear="none">

There are a few operators I have seen that have been doing some good work out there but its few and far between, many are talking about plans, but sadly, I'm not seeing much beyond plans and talk.<br clear="none">

A PLAN is meaningless if that is all it remains.<br clear="none">

I agree with you but I will be much in favor with those who start to deploy v6 like than those who whant v4 without providing any CONCRETE v6 plan.<br clear="none">
