ARIN Letter Says Two More Years of IPv4

dew4au writes "A reader over at SANS Internet Storm Center pointed out a certified letter his organization received from ARIN. The letter notes that all IPv4 space will be depleted within two years and outlines new requirements for address applications. New submissions will require an attestation of accuracy from an organizational officer. It also advises organizations to start addressing publicly accessible assets with IPv6. Is ARIN hoping to scare companies into action with the specter of scarce resources? This may be what's needed to spur adoption since there appears to be no business case for IPv6 deployment."

Nothing gets fixed until it breaks

Nothing gets fixed until it breaks so fully that people can't ignore it any longer. ARIN should just hand out the last of their IP assignment already and then we can move on with actually deploying IPv6.

A lot of the companies that have class A networks had them issued before CIDR. Also don't underestimate the size of some of these networks. Ford has a half dozen datacenters spread out around the world thousands of VOIP phones, Desktops / Laptops, routers, switches, AP, servers. Not to mention most modern manufacturing plants PLC's run on a IP network sure you will never use the whole space but do you really think they are going to re-IP a network that size. Ford also owns a class B network :)

And there's absolutely no reason that those devices can't be assigned an address from the 10.x portion of RFC 1918. None at all, except for the magnitude of the problem.

They should have planned for that so, so long ago.

Go ahead, yank 'em all back. Worldwide, the five RIRs (AfriNIC, ARIN, APNIC, LACNIC, RIPE) go through 12-14 /8s per year. Don't give yourself a charley-horse patting yourself on the back because you managed to move out the exhaustion date by 8 months.

BTW, the US Government *gave back* several /8s.

IPv4 is terminal. Get over it and get your IPv6 on.

IPv4 Address Exhaustion Is Always Be 2 Years Away

Case in point. Thought it was supposed to be 2010? Now it's 2011.

IPv4 addresses won't magically be exhausted one night. They'll just start getting more expensive.

As I keep pointing out

[wowbagger]

As I keep pointing out on each IPv6 story, there will be little motivation to move to IPv6 until you can hit major sites, like cnn.com and slashdot.org, using nothing but IPv6 packets.

We've made a bit of progress, in that now, if you have IPv6 connectivity to "the Internet", you can in theory do the name resolution entirely by IPv6 packets, now that the root name servers support IPv6.

Note to the "a little knowledge is a dangerous thing" crowd: yes, you can form an IPv6 packet with an IPv4 address, but that doesn't mean the target machine will actually be able to understand it - it is still a completely different packet type than an IPv4 packet.

So, does slashdot.org have IPv6 enabled? Does the colo housing slashdot.org's servers route IPv6 packets from the Internet to the slashdot.org servers? Can "the Internet" route IPv6 packets to the colo?

If a tech site like slashdot.org doesn't have the ability to handle IPv6 traffic, then why should I get all hot and bothered about trying to get IPv6? And if I'm not going to demand it, then why should my ISP spend the effort to supply it?

Why couldn't we just add another octect. So my new IP is 1.24.101.1.15

Fortunately, nobody in their right mind would let Slashdot design a new network protocol.
