IPv4 Will Not Die In 2010
darthcamaro writes "A couple of years ago, the big shots at IANA (that's the people that handle internet addressing) issued a release stating that the IPv4 address space was likely to be gone by 2010. Here we are in 2010 and guess what, IPv4 with its 4.3 billion addresses will NOT be all used up this year. In fact there could be another two years worth of addresses still left at this point. 'We're at about 10.2 percent (IPv4 address space) remaining globally,' John Curran, president and CEO of ARIN said. 'At our current trend rate we've got about 625 days before we will not have new IPv4 addresses available. We're still handling IPv4 requests from ISPs, hosting companies and large users for IPv4 address space, but that's a very short time period.'"
Domain squatters and the like use one IP (and one server) for thousands and thousands of domains. They're parasites but they're not using anything like a significant fraction of the available IP space.
No, this sums it up. If you'd bother to read this or an estimation done by someone else, then you'd know that the uncertainty is less than 3 months with high confidence. Of course the 625 days thing is bullshit, but saying 1.5 years +-3 months is probably what will happen, unless something really major changes don't start happening in the IPv4 process, which I wouldn't say is too likely based on the fact that it would require immediate global cooperation (see how well that went in Copenhagen).
It takes a man to suffer ignorance and smile
Be yourself no matter what they say
IPX won't die in 2010, either.
But, in all seriousness, there's a few things to remember here.
1. The v4 address space will be exhausted in the foreseeable future.
2. Reclaiming large blocks only delays that inevitability by a few months.
3. With a few exceptions, modern, supported OSes (Windows [2003, 2008, Vista, 7], GNU/Linux, all of the BSDs, OS X) support IPv6 perfectly.
4. Most of the critical applications support IPv6 perfectly.
5. The big holdup on the consumer side has been with the ISPs. The DOCSIS 3.0 roll-out is ongoing in many places.
6. The US government has mandated it. The compliance date was in 2008 for all of the Federal agencies on their backbones. It's just a matter now of getting ISP access to those sites, and configuring lower-level systems.
The luddite attitude here about this is amazing. If you're really all that concerned about it, and don't want to focus too much on the nuts-and-bolts, here's some advice: Learn BIND. Setting up your resolvers properly will spare you headaches.
I use IPv6 every day. I get lots of e-mail over IPv6 (netbsd and freebsd mailing lists, to name just a couple). I enjoy being able to ssh to all of my machines at home directly. It's here. Evaluate your crap, and see what's not going to work. Plan to replace that stuff. Most of it probably will need replacing by the time you get assigned a /64 or /48 by your ISP, anyway. This isn't rocket science. /rant
One of the quick and dirty ways to continuing to use IPv4 is to have some of the huge chunks of the address space given back. Do FORD, MIT, Apple, IBM, etc each need 256^3 addresses? (http://xkcd.com/195/) IPv4 has almost 256^4 or around 4 billion IP's that's almost one IP per person on the planet and plenty to last a *LONG* time.
