The internet will run out of IPv4 addresses within 500 days it is claimed, stressing the urgency for businesses to migrate to IPv6 addresses.

Internet AddressThe Number Resource Organization (NRO), the official representative of the five Regional Internet Registries (RIRs) that oversee the allocation of all Internet number resources, has announced that the existing pool of IPv4 addresses will run out within 500 days.

Internet Protocol (IP) is a set of technical rules that defines how devices communicate to each other over a network (like the internet). There are currently two versions of IP, IPv4 and IPv6. An IPv4 address will look something like 203.123.123.123 and is where your internet browser will visit after it looks up an web page through a Domain Name Server (DNS) (Translating www.dynamicbusiness.com.au into 122.201.71.17 which is our IPv4 address for example).

This is weird and scary :eek:

I've been hearing "two years of IP addresses left" for close to ten years now. I'm relatively confident that we will not have run out in 500 days' time.

However, I've seen lots of articles saying "you need to move to IPv6", but none of them seem to explain HOW to do such a thing. Even the first page of Google results for "how to move to ipv6" mostly consists of articles saying "hurry up and move" with no actual information on how to do such a thing.

From the information that I've pieced together, I need to wait for my ISP to offer IPv6 support before doing anything else. Is that correct?

Thanks to Network Address Translation, it's not going to run out. There are over a thousand devices inside my company between printers, phones, notebooks, servers. We only have 5 external IP addresses, and two thousand plus, inside.

IPv6 is WAY off from normal use. Your ISP will still hand down IPv4 addresses in the same manner. So, we're cool.

There's nothing to worry about, it won't run out in 500 days either. We still have about less than a decade left, since we are going to be transiting between IPv4 and IPv6 for a long time. NAT is helping big time to slow down the IPv4 consumption. There's also a couple of large A blocks reserved for breaking down into smaller classes once we finish off the current IPv4 B/C classes.

The biggest problem now is the IPv6 transition, it's going too slow. There's a lot of issues with tunneling between IPv4 and IPv6, especially DNS as well. It's going to take a long transition but we won't be phasing out IPv4 any time soon, not for another two decades.

I mean even our root DNS servers are not fully IPv6 ready yet, which is sad and we're just starting to mandate DNSSEC for the root servers next month.

As for people asking about moving to IPv6, there's no need to for customers. You don't have to do anything except wait. ISP has to be ready for it first, not you. The IPv6 move has to be done from the top down, from the biggest companies to the cable/dsl/dialup customers.

A side effect of the Compaq / Digital and the HP / Compaq mergers?

HP owns 15.x.x.x and 16.x.x.x.

And I have a map that says in the not too distant past, the US Postal Service owned the 56.x.x.x block. Maybe that's how they'll fund themselves in the future, selling subnets, and maybe hosting. They have a huge distributed set of offices. Servers in some of the key locations and they could be a huge national co-lo / cloud company. (And if anybody takes that idea from me and makes zillions, all I ask is that they buy me a stacked Mac Pro. Thanks!) :rolleyes:

well if you look it this way the general population has no reason to understand anything about the differnece between vpv4 and ipv6. It is the ISP, DNS servers, and host that will have the issues. The largest issues for companies is changing the internal IP routing for their web page.

To play Devil's Advocate:

On the other hand, the boom of smartphones and 3G data, and soon, the new applications that will be created by 4G data, are going to be creating a new drain in IP addresses.

We are already starting to see cameras that can upload pictures they take over 3G (thus taking an IP address), book readers that can access a store and download books over 3G (aka Kindle), a new generation of laptops and tablets that can hop on the 3G networks (like the iPad), phones being able to access the internet over 3G becoming the standard...

All of these devices don't get to make use of NAT.

People are starting to predict that, with LTE/4G in the next year, people might begin using it for their main internet access. But, devices connecting directly to 3G or 4G networks get their own IP addresses...no NAT.

While a business might have a thousand computers all using only one IP address...each employee in that business might be using three or four (a Blackberry, a laptop w/3G, their home internet connection, their Kindle...).

I'm pretty sure that any device you connect over 3G will go to an internal IP address allocated by your 3G provider and then be NATed to the wider internet (at least that's what happens in the UK) by the provider

It could be an option. With Telecom NZ I get a NAT address by default, but can switch to a public address by using the APN menu. I believe that Optus in Australia hands out public addresses by default.

I was thinking more along the lines of my home network. Once my ISP offers IPv6, I guess that all my local equipment would continue to use v4 unless I decided to switch it over. Is that correct? Is there anything I can do in advance on a rainy day to make the transition easier when it comes?

Apple should migrate internally to IPv6 and sell off the 17.0.0.0/8 class A range. At the moment it's worth a fortune as an asset. In 10 years it'll be worthless.

BTW, everyone keeps telling me that ARIN, RIPE etc. are getting more restrictive in what they give out. I've noticed no change in policy myself.

Well the problem will mostly be on the ISP again. Your computer does not care if you put in 12 digits or 100. It will say I want to go to that location.


A DNS server just tells you want IP to go to.

My understanding is your home network will be find to run v4 when the switch happens.

The only way to convert you system over is it would require a firmware update to your router as they are not program to handle it but at the same time 192.xxx.xxx.xxx. I know there are some other numbers that are already complete called for for calling routers and since there are so many 192.xx that is a lot of computers on one internal network before you run out.

If all your computer gear sits behind a router (hint - this applies to 99.99% of the population) then you have nothing to worry about for a good few years yet.

(Mobile devices will sit behind the routers that the telco uses)

The only people who need to worry about this are IT officers at large multi-sited companies, and ISP technical staff.

Unless your ISP can't give your router an IP because they ran out ;)

No, they'll either reuse their existing floating IP addresses if like most people, you don't have a fixed IP.

If you have a fixed IP, they'll probably assign your router an IPv6 address - dealing with them is their concern. Pretty much all modern routers can deal with IPv6. Your router will continue giving out IPv4 addresses on its internal network.

Again, the only people who need to worry are these who deal with multiple networks and WANs over IPv6.

If all you do is remote login to your home or work computer (which is more advanced than 99% of the population) some minor tweaking might be needed.

The ISP will just give you a new modem that can tunnel your home IPv4 traffic into IPv6 packets through their neywork. It won't be a problem.

The switch to IPv6 only network will not happen for decades. Both IPv4/IPv6 will co-exist for a long time.

I know that's wrong without having to work it out. The BT Tower tells us every morning how many days it is until the London 2012 Olympics. It's at just under 800 days right now.
