You shouldn't have to worry as a consumer, the ISP's such as telecom will have to deal with it.
If theres anything like a new modem required (or a firmware update) they will have to inform and deal with it well in advance.

You referring to the latest scare story on Stuff?

http://www.stuff.co.nz/technology/it-telcos/4179342/Mobile-device-boom-sparks-US-net-address-shortag...

NZ will not be running out anytime soon, many tens of years in fact! It is just the way the internet is split out and short sighted planning in the US, means some companies have millions of unused IP addresses locked in to their IP range.

In NZ we have plenty for the number of people and devices in our IP block allocated.

When change does happen many of the devices out there are IPv6 compatible and will be inexpensive for consumers to change. The large cost will be for major ISP's and core network upgrades.

That's not correct at all. We are running out just like every other country in the world. APNIC is very close to running out of IPv4. NZ does not have just one big block. Each ISP will have requested IPv4 from APNIC directly, or via their upstream provider. Some ISPs may run out before others.

The number of Internet connections in NZ is still growing - with mobile broadband probably being one of the fastest growing areas.

I believe we may have 2-3 years up our sleeves if we're lucky, but certainly not tens of years.

My views are my own, and may not necessarily represent those of my employer.

Ah, i see now, when we do run out, what actually happens?, everyone i know thinks its the end of the world and there is no internet. One news said something about ipv4 addresses not being able to communicate with ipv6 and we wont be able to chat/video eachother if one person is on ipv4 and one is on ipv6

Each individual ISP will have to roll out their own solution for the "running out of IPv4" issue. There are several different approaches available to each ISP to enable them to continue to provide services to new customers - some being stepping stones along the way.

For the purists out there, there is essentially v4 and v6 "internet"s out there, and they require some jiggery pokery to communicate (if at all). Obviously this is non optimal, and what I expect most ISPs to get to eventually is an option called "Dual Stack".

Essentially what will happen here is your modem will have to IP addresses - a v4 address and a v6 address. For any given website you'll do a DNS look-up - and dependant on whether the site is hosted by a v4 or a v6 address, your PC will send out a IPv6 packet, or an IPv4 packet. In this way everywhere is accessible. But all the infrastructure inbetween must support this (or tunnelling where appropriate).

Suggest you check out http://www.ipv6.org.nz/

Also take a read of http://en.wikipedia.org/wiki/Ipv6#Transition_mechanisms which probably explains the details much more succinctly than I can :)
