Less than 5% of IPv4 addresses left says NRO

By on October 18, 2010, 6:39 PM
In late January, the Number Resource Organization (NRO) warned that IPv4 addresses were drying up, with less than 10% unallocated -- a figure that has shrunk rapidly over the last nine months. The organization now reports that two more blocks of IPv4 addresses have been assigned, putting the number of vacant addresses below 5%.

"This is a major milestone in the life of the Internet, and means that allocation of the last blocks of IPv4 to the RIRs is imminent," said NRO chairman Axel Pawlik. He continued by urging all Internet stakeholders to take action now by adopting IPv6, the "next generation" of the Internet Protocol, which offers infinitely more address space. IPv4 (32-bit) gives up to 4.3 billion addresses, whereas IPv6 (128-bit) provides 340 undecillion addresses (340 billion billion billion billion -- that's 36 zeros).

The NRO says that five blocks of IPv4 address will be distributed simultaneously to the five Regional Internet Registries (RIRs) -- and it won't take long until they're gone based on current depletion rates. Should that occur without adequate preparation, the NRO worries of a "chaotic scramble for IPv6" that could spike Internet costs and threaten the stability and security of the global network.

Kick all the scammers, spammers and scum off the internet and we'll have plenty of addresses left.

Those "scum" are operating botnets, i.e. running their nefarious software on the PCs of unsuspecting, average Joes like you and me. A bigger problem with IPv4 distribution is companies like where I work ... we have half a public class C network all to ourselves, and we *maybe* use 6 of those 128 IPs.

I once knew a teacher, (who has an AS in IT and teaches programming/robotics), believed that every machine should have it's own public IP address...

There are so many solutions to this problem. I wouldn't be worried.

Hear, hear! And destroy the botnets!

Na, its not as worrying as they make it out to be, although I do believe the adoption rate in IPv6 does need to improve Drumatically.

I think we need to make a switch over to Ipv6....


surbey said:

I saw this article a couple of weeks ago and was dumbfounded. The delay in switching to IP6 is completely ridiculous. IP6 can provide over 5,000 ip addresses per SQUARE INCH of the planet. Why on earth did we not start switching THE DAY THE PROTOCOL WAS STANDARDIZED?!.

You forgot to add 'pron' into this 'should be kicked' list.
