What Happens if You're IPv4 Only

Light Reading

Enterprises may consider moving to IPv6 an expensive task that doesn't generate any new off-setting revenues, but as American Registry for Internet Numbers (ARIN) points out, there are negative business consequences for those who fail to adopt a v6 transition strategy.

Check them out in the infographic below:

Re: nonsense

Yea, CCNA/NP/SP were while ago, you're right. Anyway, what I wrote still holds. I can question with reason any of the statement on the poster and most of them are simply exageration or bad try to find a business opportunity where a technical issue is absent.

You might want to take a look into the Nanog preso regarding IPv6 state of things at http://www.nanog.org/sites/default/files/mon.tutorial.ebersman.ipv6_.9.pdf

and additionally try visiting Ivan Pepelnjak's blog and see how many issues of real IPv6 deployment are yet to be solved.

Re: Questions

Since no one answered your question directly, the answer is yes, but it depends on your providers, I'd like to think over half of them offer some kind of IPv6 service, but not all at the residential level.  This will change as the years progress and IPv6 becomes more important and propagated throughout the internet.

If you are just curious about IPv6 there are ways to tunnel your IPv4 connection to a IPv6 node on the internet, and you can use IPv6 that way.

Re: IPv4 shutdown
We had a pretty good discussion on this last month with Owen from HE,


Asia and other parts of the world that don't have IPv4 space to hoard are already moving heavily into IPv6.

What's most important to the migration for ARIN is content being available on IPv6.  Even at 50% growth YoY it's still only 1.5% of the internet's traffic.  What we need is more switch over to IPv6 dates for the content guys to share that risk.

Yea, no one knows when your particular org will run out, or how much gray market space will be available here in NA, but it's a painful process to get your network over to IPv6, not only from a network perspective, but from a product and OSS/BSS perspective as well.  I like to think it's a good 2 year process.

Anyone who's hasn't deployed and not planning for it is either blind, very short sited, or not in charge of having worry about it.

And no, I'm still not a fan of LSN.  And there is no shut off date.

IPv4 shutdown
Correct me if I'm wrong, but there is still no real IPv4 shutdown date, right? A shutdown deadline is powerful motivation to change.

The whole set of pictures is an unbelievable nonsense. IPv6 penetration is close to 0, many operating systems and a lot more applications don't handle IPv6 properly, adoption will take plenty of time.

Come back with your FUD in 5 years, let's see how hot it's going to be then.

Can ISP service bring IPv6 address from now to be use?
