How many users have access to IPv6 connectivity?

Since this is NANOG, let's talk about North America.

Canada is way behind, just 0.4% deployment.
The U.S. is one of the top countries, in both number of users and number
of top web sites.
Three of the big four U.S. ISPs have double-digit deployment. It's not the
"vast majority" yet, because:
1. Older modems don't support IPv6 (older than, what, 2008?).  As those
churn, counts will rise.
2. Older gateways, especially consumer-owned retail devices, don't support
IPv6.  Churn would help, if new retail gateways supported IPv6.
3. The <10% of people with MacOS use IPv6 half the time (more or less)
that it's available.

I can't find statements right now, but I think those big three are all
90% deployed, if you don't count rolling trucks to replace modems.  The
number of IPv6-capable users is several times higher than the number of
people actually using IPv6, and I don't know why.

Verizon Wireless and T-Mobile have great IPv6 deployments, too, maybe a
couple more years for older handsets to age out.  Still, >50% of VzW LTE
devices use IPv6 now.



Everything I have at the colo is dual stacked, but I can't reach my own
systems via IPv6 because my business class Verizon Fios connection is
IPv4 *only*. 

Well there's your problem.


Yes, Comcast is in the process of rolling out IPv6, but my
Comcast circuit in Washington DC is IPv4 only.  And I'd suspect that
everyone with Time Warner, AT&T, Cox, etc are all in the same boat.

I think all of those companies offer IPv6 on their business-only services
(e.g., fiber, ethernet, etc.). For access methods shared with residential
users (i.e., DOCSIS, DSL), it's not rolled out yet. . . RSN.


Whether the reason for the lack of IPv6 deployment is laziness or an
intentional omission on the part of large ISPs to protect their income
from leasing IPv4 addresses

ISPs want to protect their income by continuing to turn up services.

Can't tech news sites *please* run dual stack while they're spouting
end-of-IPv4 stories?

<wishful thinking=on>

I would love to see a few more properties do IPv6 by default, such as
ARS, Twitter and a few others.  After posting some links and being a log
stalker last night the first 3 hits from non-bots were from users on
IPv6 enabled networks.

It does ring a bit hollow that these sites haven't gotten there when
others (Google, Facebook) have already shown you can publish AAAA
records with no adverse public impact.  Making IPv6 available by default
for users would be an excellent step.  People like AT&T who control the
'attwifi' ssid could do NAT66 at their sites and provide similar service
to the masses.  With chains like Hilton, McDonalds, etc.. all having
this available, it would push IPv6 very far almost immediately with no
adverse impact compared to users IPv4 experience.
