Commercial IPv6 Service In Australia

(2,092,000^2*4*PI)=6.187*10^13 (again, significant digits are your friend)
2^128=3.402*10^38
(3.402*10^38)/(6.187*10^13) = (3.402*10^25)/6.187 = 5.499*10^24
Your answer was approximately 6*10^22, so off by a factor of 100.
Still, anyway you slice it, that's a fuckload of IPs. Which is good, because we certainly don't want to run into the "nobody could possibly need more than 512k of ram" problem. This way, utilizing all those IPs would be practically a physical impossibility, at least as long as we're contained within this solar system.
Of course, this doesn't mean the "thousands of IPs per square foot" people are WRONG. After all, 5.499*10^24 is 5,499,000,000,000,000,000,000 thousand IP addresses per square foot. That's many many many thousands :)

Actually, satellite links are just about the most affordable form of broardband available outside Sydney, Melbourne & Brisbane. Telstra cable is way too much, and Optus hasn't cabled anywhere else, but you can get sattelite access for around $40-$50 a month.
Of course, sattelite internet is actually a pretty crap form of 'net access - it is high lag, ties up a phone line, and is only fast one way.
For those of you who would like to implement ipv6 on your systems, there are howto's available at http://www.ipv6.org/howtos.htmlAlso check out the USAGI Project
But we never told you. Just like we never told you about our nukes or our kamikaze kangaroo teams. All that fubared censorship legislation you've been reading about? It's a ruse.
We have big plans up here. Yeah, that's right: up. Australia's ON TOP OF THE WORLD, damn it! Your northocentric imperial maps are upside down, but you didn't realize it. Just like you didn't realize about the nukes. You'll learn all too soon. Mark my words.
But I've said too much.
Look, everybody, more numbers! It's a huge '128-bit address space'!
Suddenly, the internet is faster, my computer is smarter, the world looks brighter, slashdot posts are more intelligent....
Nah. Everything still sucks.

In IPv6 you don't need to. RFC 2462 defines the mechanism for Stateless Address Autoconfiguration which uses the Neighbor Discovery mechanisms defined in RFC 2461 for automatically configuring the host. Basically all IPv6 routers periodically send Router Advertisement multicast packets to the all-nodes multicast group. The content of these messages is information on how the host should configure itself ('M' flag for managed - i.e. DHCPv6). If SAA is used, the host can create an IP address for itself by prepending its Interface Identifier (E.g. EUI-64) with the prefix contained in the Prefix Information option. Hosts can at anytime send Router Solicitation messages to request RAs. The IP source address in these messages is the IID prepended by the well-known link-local address prefix. That means, each IPv6 has a scope, link-local, site-local or global.
one, yes, Johnny uses the net.. he has a stupid talk radio show and people are always asking him if he has read something another on the net and most the time he has. two, he was specifically talking about Australia.. he was saying that the divide between the haves and the have nots of infotech must be eliminated if Australia is to move forward. Howard has always been a "we are the smart country" type. It gives him an excuse to fuck over farmers and miners.
How we know is more important than what we know.
