IPv6 and You.
 

Are you aware that IPv4 allocations will be depleted in less than two weeks with the RIR's? This means no new allocations will be given out to companies. The remaining 7 /8 netblocks will be distributed to the RIR's 1 each and have very strict rules for allocation.

Why would this effect you? Simple

• "SEO Hosting" will become a lot more expensive and or gone completely.
• Hosting in general will go up in price due to supply/demand of IPv4 Space
• People who utilize bulk IP space is going to go up dramatically in prices and/or shutdown
• Software will break with IPv6 unless it can already handle it, i.e traffic scripts etc anything that logs IPs deals with IP addresses.

Is your current host utilizing IPv6 and running it in a dual stacked environment? You should be getting a IPv4 and a IPv6 IP with every machine/request/setup that you do. IPv6 is not hard and can run in parallel with IPv4 so why not start utilizing it?

At first people wont care or really matter, in probably 2 years reality will strike with everyone because their net blocks they have in reserve will be depleted and then panic will set in. Most hosting companies these days run dual stacked environments and are setup to handle IPv6 the problem really lands on end user ISP's who are just god awful slow at adapting. Comcast to my knowledge is the only ISP thats testing IPv6 so atleast they are one up on most networks. While yes there are ways at recooping IP space from say China who happens to be one of the biggest hogs for IP space but this just buys time before it has to happen.

Some people are calling IPv6 the newn y2k "bug" but this is nothing like the "y2k" problem. IPv4 is running out and will soon be gone. Its time to adapt and move forward. People on NANOG have been talkinga bout a IPv4 blackout date, in other words the day most networks should be fully switched over to IPv6 and the date was suggest for December 31st 2019. Yes its 8 years away but a LOT can happen in 8 years. This is real people so wake up, start poking your hosts and software companies to see if they support IPv6 yet, if not bug them until they do. Would you rather be one of the few/first sites online when google starts seeing native IPv6 on its searches and indexes you on IPv6 when there is little competition? or be stuck in a sandbox with everyone else.

I lose sleep at night over this shit...

No need to rush getting an IPv6 IP, since there's, practically speaking, an unlimited supply of them. Get them as needed.

Running both IPv4 and IPv6 right away would seem the prudent thing to do, but it comes with a tradeoff of loss of visitors. While IPv4 and IPv6 are similar in name, they are technically very different; not backwards compatible...

And so if a visitor has some IPv6 connectivity (ie. their OS and/or ISP), but their router and/or something along the line doesn't do IPv6 correctly, instead of falling-back to IPv4 (as one would reasonably expect), the visitor will likely get a very long pause (many will click-off thinking the page is broken) and/or get a site not found error.

In short, if running IPv4 / IPv6, expect at least a 10%+, and potentially far more, drop in visitors. For more info, read the various news articles regarding the tough challenges / tradeoffs Yahoo and Google are confronting as they work to transition over to IPv6.

I'm sorry but you either support IPv6 and AAAA records which DNS would utilize/pickup or you wouldn't. There is no pause/stop/start falling back to IPv4. You either support IPv6 and AAAA or you don't. Please show me some proof that this happens. You might be thinking of someone doing some sort of failed IPv6 to IPv4 tunneling or NATing which is not native IPv6. I have never seen someone "automatically" fall back to IPv4 if they are using IPv6 natively. You would be rather shocked to see DNS queries request AAAA records for your zones if you paid attention to it.

My server is ipv6 ready and already has a /56 block assigned.
DNS is ipv6-ready

It's just that I've done sod all with the web server to make it ipv6-aware, so no point in 'turning it on' so to speak.

Those ip numbers though are well, just a bitch to remember!

You're correct about pure IPv6 ... no delays, no problems.

However, many people have lousy home routers, that while claiming to support IPv6, don't always do so in the way one would expect. And that's not the only issue either.

See this article regarding the challenges Yahoo is facing ...

I've been hearing IPv6 doomsday stories since 10 years ago

Its about to become real unless IANA can get China to give back some netblocks, APNIC is the largest single RIR for IP space.

Theres going to be a huge black market for IP space

Yes its true that most of these linksys home routers do not support ipv6, as stated in that article those users will have problems and will have to upgrade their hardware. Yahoo's problem isn't really a problem for them its their users that have the problems due to legacy hardware.

It would surprise you to hear that so many so called "enterprise" firewalls don't even support ipv6 yet. The first question out of a companies mouth to a vender is, do you support IPv6? if not then they don't have interest and this is driving venders to start working on it. No one can start utilizing Ipv6 effectively until the hardware required can support it and this is the longest/slowest part to develop.

That already exists.
