Hi, In answer to a ticket entitled "Not getting an IPv6 prefix today", here is what the help desk told me:

...

Currently XXX have IPv6 services turned off due to some ongoing investigations with this service.

Once this is turned back on you will be able to get an IPv6 address again.

and in response to my follow-up bleat

...

As IPv6 is not the Primary access method we offer on our connections this does not need to be updated on the network status page.

IPv6 is not a fully released product therefore it is still going through testing and this is why we are currently unable to apply static IPv6 address

(I didn't ask about a static address and don't want one.) This morning, I still have no IPv6 service and the XXX status page still says "OK - No Known Network Problems". Now, since I've had stable IPv6 service for a long time and it often gives me better response times than IPv4, I was a bit annoyed by this. Isn't it time that people consider IPv6 to be the primary access method, and IPv4 to be a legacy solution? Grumble. I need to fire up SixXs again, then. Brian

Luckily not all providers think like this. Here's a graph of the IPv6 penetration in Norway recently https://www.vyncke.org/ipv6status/plotpenetration.php?country=no All because of an "increase in the number of Telenor retail ADSL, VDSL and GPON customers with native dual stack access." A nice writeup with technical details here. http://lists.cluenet.de/pipermail/ipv6-ops/2014-November/010244.html Dean On Sat, Dec 13, 2014 at 9:56 AM, Brian E Carpenter wrote:

Norway? Close to us in population sure, but they are only following along in Belgiums footsteps. https://www.vyncke.org/ipv6status/plotpenetration.php?country=be In Q4 of 2013 Belgium were still futzing around with IPv4 and announced a "wonderful" market growth rate of 1.3% (~50,000 users, up from 0.6% woohoo!). In Feb-Mar 2014 Belgium rolled out IPv6 country-wide and announced a Q1 2014 market growth rate of 22.6% (~700,000 users). For those who have been ignoring it; * IPv6 has been growing exponentially since 2007. * It has now past 5% of Google and Akamai global customer base. * IPv6-only CDNs, ISPs and "cloud" services are popping up like wildflowers everywhere. * who is going to be the last ISP jumping on that customer gravy train?

I chose this particular ISP specifically because they offered IPv6 IA_PD by default to all customers. Since they're no longer able to do this, I need to re-evaluate my choice of ISP. But who else offers dual-stack by default in NZ? I haven't found any good source of information that outlines what the various ISPs offer. ipv6.org.nz hasn't been updated for a while. There's a couple of providers that still seem to be running 'trials' - but those pages haven't been updated in years. That doesn't exactly fill me with confidence. Does that mean it could be switched off for an extended period, like the situation here? I guess I need to go and ring around all the different ISPs, and put together my own table, showing current state. Unless someone else has some up to date information?

Well, I've been waiting for an explanation of the following statement from their help desk, but since they have gone silent on me, I wonder if anyne here can make sense of the following:

...

Due to ongoing issues reported by customers in relation to IPv4 to IPv6 Translation around the country and a handful of international sites we have made the decision to disable the service on our network temporarily.

I mean, in which universe can such issues be mitigated, or even affected in any way, by switching off native IPv6 support? Regards Brian On 14/12/2014 12:55, Lindsay Hill wrote:

If we're all talking about the same ISP (SNAP, who I have good things to say about in general), there are a number of geekzone threads about IPv6 problems with their fritzbox modems that they've been issuing. Possibly they decided it was all too much effort and gave up. Having more customers on IPv6 (presumably) means more customers bypassing local on-net CDN's for content too. Does Akamai support IPv6 for all content? Until such time that all network operators consider IPv6 not-as-important as IPv4, what's the point of using it? Moving to dual-stack IPv6 (I cant, SNAP wouldn't give me a static IPv6 on static IPv4 anyway) means getting sub-optimal routing (path's and CDN end-points), as well as router quirks, etc. Perhaps if Truenet added IPv6 metrics to their ISP testing suite, this might push some ISP's into caring more. There is no NZ ISP that fully supports IPv6 on DSL/UFB that I am aware of. Regards, Joel van Velden On 2014-12-18 11:13, Brian E Carpenter wrote:

What exactly do you mean by "packet errors"? I've seen no such problems and (until they brutally switched it off) I've had equal or better performance with IPv6. It's very frustrating that the ISP won't give a proper explanation, because such problems need to be exposed, understood and fixed. Brian

I saw a lot of retransmits on TCP streams over IPv6, and wireshark was showing weird stuff in the ether header... but only on the wired ports, as wireless worked fine. I may have a pcap lying around if you're interested, although I almost guarantee once I share it you'll see that I've been looking at a red herring and completely missed the real problem! tl;dr it seems to be an issue with the wired ethernet ports on the CPE rather than anything in the core On 19 December 2014 at 08:06, Brian E Carpenter wrote:

Google has some interesting stats on per-country IPv6 adoption here: https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-ado... Note that their measurements show a significant impact on latency and error rate for IPv6 in NZ. Also interesting to see the US adoption rate - 11.75% was much higher than I expected, and puts our 0.62% to shame. I'm pleased that Snap has IPv6 working again, but I will still be putting together some info on IPv6 availability across NZ ISPs. A little summer project I guess. I'll try and get a reasonable sample of ISPs together, and then hopefully we can keep it up to date as more ISPs enable IPv6 for consumers. On Fri, Dec 19, 2014 at 8:13 AM, Sam Russell wrote:

Lindsay has been in touch and I'm happy to host his findings on www.ipv6.org.nz when he's done. Happy Xmas all On Mon, Dec 22, 2014 at 10:46 AM, Lindsay Hill wrote:

Google has some interesting stats on per-country IPv6 adoption here: https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-ado...

Note that their measurements show a significant impact on latency and error rate for IPv6 in NZ.

Also interesting to see the US adoption rate - 11.75% was much higher than I expected, and puts our 0.62% to shame.

I'm pleased that Snap has IPv6 working again, but I will still be putting together some info on IPv6 availability across NZ ISPs. A little summer project I guess. I'll try and get a reasonable sample of ISPs together, and then hopefully we can keep it up to date as more ISPs enable IPv6 for consumers.

I saw a lot of retransmits on TCP streams over IPv6, and wireshark was showing weird stuff in the ether header... but only on the wired ports, as wireless worked fine. I may have a pcap lying around if you're interested, although I almost guarantee once I share it you'll see that I've been looking at a red herring and completely missed the real problem!

tl;dr it seems to be an issue with the wired ethernet ports on the CPE rather than anything in the core

If we're all talking about the same ISP (SNAP, who I have good things to say about in general), there are a number of geekzone threads about IPv6 problems with their fritzbox modems that they've been issuing.

I've recently turned off IPv6 at home as I was getting frequent packet errors that meant anything IPv6 enabled (google) took an age to load and often timed out, and completely broke windows updates.

What exactly do you mean by "packet errors"? I've seen no such problems and (until they brutally switched it off) I've had equal or better performance with IPv6. It's very frustrating that the ISP won't give a proper explanation, because such problems need to be exposed, understood and fixed.

Possibly they decided it was all too much effort and gave up.

Having more customers on IPv6 (presumably) means more customers bypassing local on-net CDN's for content too. Does Akamai support IPv6 for all content?

Until such time that all network operators consider IPv6 not-as-important as IPv4, what's the point of using it? Moving to dual-stack IPv6 (I cant, SNAP wouldn't give me a static IPv6 on static IPv4 anyway) means getting sub-optimal routing (path's and CDN end-points), as well as router quirks, etc.

Perhaps if Truenet added IPv6 metrics to their ISP testing suite, this might push some ISP's into caring more.

There is no NZ ISP that fully supports IPv6 on DSL/UFB that I am aware of.

Well, I've been waiting for an explanation of the following statement from their help desk, but since they have gone silent on me, I wonder if anyne here can make sense of the following:

I mean, in which universe can such issues be mitigated, or even affected in any way, by switching off native IPv6 support?

In answer to a ticket entitled "Not getting an IPv6 prefix today", here is what the help desk told me:

...
Currently XXX have IPv6 services turned off due to some ongoing investigations with this service.

I use them too and have been through a similar experience with the help desk. Their answer on Dec 5th was: "At the moment our network engineers are still investigating this issue and we will not be updating the network status page until we know more about the problem." I responded that "that custom and usage suggest that issues regarding the network would usually be advised to users as they occur rather than once they are resolved". They "noted" this response. Still no IPv6 tho' Robert Gray
