Level of IPv6 Usage Is Vanishingly Small

An anonymous reader writes "The impending IPv4 address allocation shortage has led to a lot of speculation on the future of IPv6 (including here). A new study says that Internet IPv6 migration is not just going slowly — it has basically not even begun. After spending a year measuring IPv6 traffic across 87 ISPs around the world, the study concludes 'less than one hundredth of 1% of Internet traffic is IPv6... equivalent to the allowed parts of contaminants in drinking water.'"

Makes me happy

It may be just me, but I always felt IPv6 is a solution looking for the problem.

There is a reason IPv4 is so well entrenched. Other than availability of software, hardware and services, it is convenience of handling IPv4 in all those things. This is what permits developers to create all those wonderful products, administrators to effectively administer them and users to enjoy them. A primary reason to that is IPv4 address size - it is 32 bit which is natively handled by all current hardware, and easily remembered by humans (short term) in its quad decimal form.

IPv6 has neither of these features. It is difficult to deal with in software (I know, I do this for a living), does not fit into any native data type (and won't until we move to 128 bit architectures - which does not seem to be very soon), cannot be remembered or used by a human (so effective administration requires magic automatic tools), does not give itself with any convenience to routing related data structures (like radix trees). All this for dubious benefit of addressing directly (in non-hierarchical manner) of every toaster in the world. This is directly opposite to the way the Real World operates (i.e. your home has an address, but noone gets to talk to your toaster directly without going through you first.

If I were solving this, I'd suggest separate and non-directly routable IPv4 address spaces for separate countries (and, perhaps, for other entities). And lots and lots of NAT or proxying. Of course that is kind of what is happening anyway.

China would be happier that way too. In case of cross-border cyberattack, just cut external links and your country is self-sufficient and interconnected :)

Anyway, I am ready to bet some cash that IPv6 will never become a major transport protocol.
I know I will do whatever I can to keep it far far away.

Should have gone to A.B.C.D.E.F.G format.

We could have even just added a 3 more positions in the address and assumed a default of 1.1.1. as the default prefix if none was given. That would have given us 16 million * the current 4 billion addresses - 64 quadrillion addresses.

At the risk of repeating the 'no one needs more 640k', I'd have to say that I think 64 quadrillion is more than usable for the next several years. The upshot is that it would have been much easier to deal with that. From a pragamatic viewpoint, there's a whole lot of software out there invested in the dotted quad format. Modifying that to deal with a few more X.X.X places wouldn't have been as hard (think GUIs that check IP validity, for example) as moving to IPv6.

Lame excuses, perhaps, but I think we'd have seen much faster adoption to a format like X.X.X.X.X.X.X because it's an incremental, not radically different.
 

So how do I switch to IPv6?

I'm actually in one of the rare areas that have more than one ISP. We have three available here. Our current ISP doesn't implement IPv6, so I can't use it. I checked with the other two. Neither of them allows IPv6, either. None of the three admits to any plans to implement it.

Most people have only one ISP, of course. What incentive does that ISP have to permit IPv6? I mean, here where we have three ISPs, none of them has an incentive to do it.

I don't see how we can ever switch to IPv6 until the ISPs stop dropping all IPv6 packets, and start forwarding them properly. And that clearly ain't gonna happen without a bit of "government regulation" ordering them to do it or else. But with the current political setup here in the US, that ain't gonna happen, either.

Anyone have any idea how to persuade the ISPs to come around?
