IANA ipv4 address space exhausted

They're gone http://ipv6.he.net/v4ex/sidebar/?

Only because they got down to five blocks (the 6th & 7th being requested by Asia Pacific earlier this month, activating a previously agreed rule that IANA would automatically hand out the remaining five (one to each region).

But, yup that's it; all blocks handed over (less than around 80 million left - from the final five handed out).
IPv6 here we come!
