ARIN warns that IPv4 addresses will be depleted in 2 years

The American Registry for Internet Numbers (ARIN) board of trustees has decided to start contacting the CEOs of IPv4 block holders advising them that IPv4 addresses will be depleted within the next 2 years and that they should move over to IPv6.

ARIN will also start toughening the vetting of requests for additional IPv4 block allocations from the 18th May.

IPv4, or Internet Protocol Version 4, is currently the core addressing system of the Internet but because it has a limited number of addresses, a theoretical maximum of approximately 4.3 billion (232), we are in danger of running out. IPv6, the only real contender to IPv4, is able to address 2128 addresses, or approximately 252 addresses for every observable star in the universe.

arrrgh can't we get ipv6 over and done with? I'm sick of having to port forward, I don't care that the addresses I'll have to memorise will be like 4 times longer AND hexadecimal...

Senator Ted was right, the inter tubes was like an old flatbed truck with one too many hay bales loaded on it. Just waiting for an axle to break. Too bad our local ISP isn't ready for tomorrow and we're kind of stuck. And with the way the economy is taking a dump, no IPV6 ready competitor will be showing up soon.

Ya getting new blocks of IPv4 addresses has been a major PITA lately. They're requiring justification sheets for even the simplest requests now.

IPv6 brings a lot of improvements, hopefully NAT issues will be reduced. Remembering that long string will be hard though.

I for one just want a faster internet connection. Roadrunner blows.

And where our branch office is located, it's rebranded as Brighthouse Communications.

We're always having to deal with the candle blowing out.

yeah, and how fast re backbones upgrading or core ISP's upgrading? they seem to be the big lag in IPv6... at least with cable networks with the deployment of DOCSIS3 the modems all support IPv6 out of box... just to get the network providers to turn the darn thing on......

And it looks like that time is running out.

We've been hearing about this for years, but people and governments don't really understand what this means.

I have to say, not looking forward to IPv6. I had a sneak peak into IPv6 when I was learning about IPv4 at University, and well, an IPv6 address looks crazy.

It's better in the long run, but wow, it looks crazy complicated.
