In less than a year, the world will run out of internet addresses and inaction by internet providers could lead to broken applications and more expensive net connections, experts warn

Bah! What a bunch of worryworts! If they'd gotten off their rockers they could have ordered their very own IPv6 addies. I got mine, you got yours?
Ponder this: there will be so many IPv6 addies available that every article of clothing we own will have it's own address.
Also ponder this: why did we go from IPv4 to IPv6? What happened to IPv5?

I hope you're kidding......but in case you're not: the number six is not a version number, it's based on he mathematical standard for the protocol, so the missing "5" is not "missing" at all. They could have used a larger base number, like 10, or 36, but with 6, the available IP addresses will be in the trillions.

Billy, I hope you're kidding.....but in case you're not: http://compnetworking.about.com/b/2008/11/05/what-happened-to-ipv5.htm That gives a pretty short description of what happened to 5.
I'm not sure what the "mathematical standard" is but maybe it's something like decimal or even hex.
I actually use this question with my students. The responses are funny. One student even took the time to explain that "Einstein was getting old and had Parkerian Disease."

[snip] the available IP addresses will be in the trillions.An IPv6 address consists of 128 bits, therefore allowing an astronomical number of machines. This is equivalent to the value of 2 raised to the power of 128, a number with nearly 40 trailing zeros.
"Trillions" doesn't begin to describe it

offlineMemberThe addresses look different as well, so some code that needs to use them will break. I discovered that testing the same Java code on OS-X (IPv6) and my work XP (IPv4) machine.

I discovered that testing the same Java code on OS-X (IPv6) and my work XP (IPv4) machine.That's only a writing convention. The 32 bits of an IPv4 address can be written as 4 small numbers separated by dots, and the 128 bits of an IPv6 address could just as easily be written as 16 small numbers separated by dots as well. Using hex digits and separating colons is just a convenience to make the two address types easily distinguishable. Internally both types of addresses are handled as a string of bits anyway.

Because computers grok numbers well, there are several methods of writing IP addresses that are functionally equivalent.
http://www.microsoft.com Domain format
http://65.55.21.250 Dotted decimal format
HTTP://1094129146 Decimal format
http://0x413715FA Hex format
http://01000001.00110111.00010101.11111010 Dotted binary format
HTTP://0101.0067.0025.0372 Dotted octal formatAll of these IP addresses lead to the same location. If you click on them, they'll probably work for you. The binary doesn't work for me but the others do.
