For what it's worth, FX has been doing IPv6 natively on pretty much all customer connections for several years, both the WAN product and the ISP product.
Standard prefix allocation of /56, static allocations.

As part of that we have native V6 enabled DNS servers and NTP servers available as well if you want to use em.

Not all customers (or even most) are using it, but it's there and ready to go when they want to, and doesn't require any additional provisioning because it's already done as part of the initial build.

Operationally wise, there were some nasty bugs in some older IOS versions which have been fixed in the more recent releases which were potentially a show stopper as far as using IPV6 on your management network - the SNMP and TACACS support was busted, so if you're using ME3400s and 891s and so on you'll need a pretty recent IOS if you want to go V6 management.

Statistics wise I don't have solid numbers, but it's a non-trivial amount of v6 traffic passing over the various networks. There are a few graphs I can see which have peaked briefly over 100Mbit/s of V6 in the last week. There are OIDs available from some devices which will give you a seperate v4/v6 breakdown if you're trying to graph it, but not all have that feature, it's a tricky thing trying to measure this but it does seem to be on the increase.

After last year's IPv6 issues, I was wondering what the status is of IPv6 support across NZ ISPs. I couldn't find that data in any one place, so I've been pulling it together myself, into a Google Sheet:

This is primarily focused around residential ISPs, and the status of their IPv6 support for 'regular' customers. I'm interested in three things:

* Is IPv6 supported - fully or trial? 
* What prefix lengths are given to customers
* Are static allocations available?"

I've got data on 11 ISPs so far, with requests out for another 3. This covers the majority of end-user connections in NZ. There are of course many more niche ISPs, and I'm happy to add their info. You can see that support is generally poor, which is probably why Google says we're only doing ~0.6% IPv6 traffic.

Comments + Updates welcome. Once I've got a bit more data, this will probably go into a more permanent home. If we get enough data, we could break out into residential vs business vs co-location IPv6 support.

I am aware of at least a couple of ISPs that are doing IPv6 trials, and when they go live, it will significantly shift the overall IPv6 penetration rate in NZ. But those trials are still mostly internal only, and you can only get on them if you know the right people. If the regular public can't get onto those trials, then I think they should be listed as "Unsupported" - too many ISPs have made noises about running trials years ago, but never got around to actually launching. You know who you are.
