arstechnica.com — A little over a year ago, I wrote an article about the IPv4 address consumption with the subtitle IPv4 Address Space: 2.46 Billion Down, 1.25 Billion to Go. A week ago, we reached the magic number of 2.7 billion IPv4 addresses used. With 3.7 billion possible addresses,¹ this means we now have less than a billion unused IPv4 addresses left.

If the yearly increase is 0% then we should never run out if my math is correct...how does he figure 2013 if there is no yearly increase?

I think alot of bulls**t can be removed from the Internet to free up some IPs. Fox news and CNN would be a start.

lolcat32, I do not need to google it. I know that IBM originally said that there might be a worldwide market for 5 computes. Also, Bill Gates has been quoted (even though he now denies it) that "640K should be enough memory for anyone." Why not add in predictions using Moore's law and how a computer is going to make a paperless office a reality.That fact is that people are consistently wrong with their expectations. Even ridiculously large numbers will eventually be used. Back in 1981, when no one was one the internet no one thought that 4 billion IPs would get used so soon. If you have used computers for any length of time, you would remember that buying large hard drives used to be a hassle because at a certain size OS's would not support something larger and BIOS also could not handle all capacities. (e.g. Win2000 (unpatched) could not handle anything larger than a 128GB drive.)The fact of the matter is that whenever you have a finite resource, eventually it will all be used. If it is excessively large, people will come up with new ways to use it until it seems very limited.

Who on earth decided it was wise to give a cellphone a public IP address?Well, I don't care. I'm going to have some fun net-scanning and remote-hacking your iPhone.No, I'm kidding. 3G phones do not get a public IP. You're an idiot for thinking they do.

"Its true, you can stretch an 1 public ip throughout 254 private IP's"That statement is so asinine, I don't even know where to begin with it. First off, your statement assumes that having a /24 on the private side is the only possibility. Do you really think that NAT can give you everything you get from a public IP. Really?"If you actually knew how to implement dynamic nat, Which would actually be PAT (port address translation) in the IOS then you would know what the f**k your talking about."Ahhh...I see. So PAT is the reason you think that NAT is some kind of panacea. Ever think that maybe you'd want to have, say, 2 or more servers listening on the same port? Like port 80 maybe?"But I guess passing the 640-801 exams means notthing"You're right. That does mean nothing. They hand out CCNA certs like candy these days. If you were a CCIE, I might be slightly impressed."Go play with your DLINK network."No thanks, I'd rather play with the 6509 that's sitting on my desk right now.

Damn. I thought the 5 computers comment was dissing Itunes DRM.

@PhuckedYou've clearly not heard of the WRT54GL then, brilliant piece of hardware.
