IPv4 Stash Opens for Carriers

You can put aside those images of carriers crawling through the desert, thirsty for IPv4 addresses. A reserve pool of 4.2 million addresses has opened up, intended to ease the transition to IPv6.

The American Registry for Internet Numbers (ARIN) and the Internet Engineering Task Force (IETF) saved up the addresses and are now making them available mostly to service providers, although others might be allowed to use them as well, says Chris Donley, project director of network protocols at CableLabs .

This is not meant to be a way to weasel out of IPv6. The addresses are meant for IPv6 transition projects such as carrier-grade network address translation (NAT), Donley says.

Donley explain some details in the video below, shot at Ethernet Europe earlier this week with Light Reading's Carol Wilson.

"You can put aside those images of carriers crawling through the desert, thirsty for IPv4 addresses."


Wow, that image had never come to mind, put you certainly added new optics to it.


By the way, how far (as in time) will that stash of IPv4 addresses carry us considering the market for smart phones, tablets is growing?

Why thank you.  :)  Just trying to add some color to an otherwise dry topic.  (Groooan.)

I don't think the reserve is meant to last very long, since it's a transitional tool only. I found what I think are the IETF minutes in which the ARIN proposal was discussed ... scroll down to "Shared Transition Space" and you'll see that the issue of the block being too small was discussed.


There seemed to be plenty of concern about the reserve giving people an excuse to delay IPv6 even more. Which might actually happen.

There is a lot of space to reclaim if desired by the way.  They can make lots more IPv4 available if they want to, but they don't.
