Zeon: The point is that if content providers aren't IPv6 enabled then there is little reason for consumers to switch. Considering how the latest cutting edge technology is to this site I think, even if there are hardly any visitors you need to make a start. Is everything still in place for when Datacom do get IPv6?

Yes, just need to add the IPv6 address and can keep running as before...

People need to understand what the numbers mean with things like the ipv4 rundown clock, That is the estimated date that IANA will hand out the last /8 range to a RIR (APNIC etc) From there the RIR's still have a /8 or two left to hand out, Its widely accepted that it will take RIR's 6 to 12 months from the last IANA delegation for them to run out.

So we're 8ish months away from IANA exhaustion and 15 months away from RIR exhaustion, What happens after that is anyones guess but there are a couple of options I know off the top of my head:

IPv4 Market place: A very, very bad idea and a huge mess. Basically those that have free space sell it but the problem with that is it will explode the global route table which requires router upgrades etc etc, Will cause a few problems, GEOIP'ing is dam near impossible in this case aswell

NAT444: Basically double nat'ing, The public v4 address you normally get on your router becomes a private IP, Kiss goodbye to running your own servers etc.

There's a couple of other options around, All of them have their pro's and con's, I would hope that by no most ISP's have a plan in place for v6 and are in the testing phase by now

Most problems are the result of previous solutions...

All comment's I make are my own personal opinion and do not in any way, shape or form reflect the views of current or former employers unless specifically stated

The market place also staves off the inevitable for only a short amount of time.

LSN (Large Scale NAT, aka Carrier Hosted NAT, aka Carrier Grade NAT) has even more problems than that, including not being nearly as scalable as people like to think.

But the real problem is not just YOU being able to get an IPv4 address, it's when someone you want to talk to can't get one. That means that you need to have an IPv6 address in order to talk to them. The technical term to describe NAT46 (4 to 6 seamless interworking) is 'broken', so you need to acquire IPv6 capability. In other words, if an organisation has an adequate supply of fissionable blasting materials[1] IPv4 addresses for the foreseeable future and thus thinks they don't need to worry, they are mistaken.

There are already significant numbers, in absolute terms, of IPv6 only hosts, but as a percentage of the Internet they are currently tiny. That's going to change rather soon now, at which point if you don't have an IPv6 address, a rapidly increasing amount of the Internet will be dark to you.
