Re: [nznog] Primary access method

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?
