I went on an IPV6 course in 1998, is it finally happening???

The real sign the world is ending is that IPV4 is about to run out...

I hate to verify my ignorance of the modern world but, what is a IPV4?

Hi Tom,

IPV4 is the system that allocates IP addresses to computers and all that gubbins. In short, they designed the system so that it would provide about 4 billion IP addresses, a unique ID for every computer and internet enabled item on the internet. It's a 32-bit system. This doesn't include all the computers and stuff that have private IP addresses behind routers. We are rapidly approaching that limit. This is called the dotted quad... like 82.18.163.143

The replacement system is IPV6. They have been trying to get acceptance for if for years (around 1998 or so, I think), but the ISPs and others have been dragging their heels over it's implementation. It's not an unlimited system, but may as well be for it provides squillion's of numbers to use (technical term there, lol!). Honest answer, I'm not sure, and haven't got time to look it all up before going to work. It comes in the format - de80::ac97:3162:55b5:554f%12 - a little more complicated to understand, but provides a far larger number of addresses.

The links will provide more information, and i may check them out myself later after work...

Giz.

Facebook had better never go down. I mean what's going to happen to my farm there?

When will cars switch themselves on and warm up with a click from a computer?

I can buy one now to work with a smart phone. It gets cold here, eh?

How long will IPv6 last???

That will be market driven. There are a zillion (another technical term) ways around the limits of addresses, already in use on distributed buses in mobile applications. The same thing happens there - somebody thinks up a bus standard with "way more addresses than anybody will ever need" (famous last words), and then the users saturate the addresses within a few months.

The cheap and nasty way around this is to create devices that are local bus controllers, with their own set of addresses below them. A typical message in ARINC/IEE/MIL-STD/Canbus today might look like:

{start block}{for address X}{instruction}{end block}

X is a device using the "standard" addressing system. It decodes "instruction" and figures out it is supposed to turn on/turn off/whatever sub-device X.1234. Depending on how much people are willing to pay, and how long your messages are allowed to be, you can overnight increase the number of bus addresses by a factor of 8, 16, 32, or whatever.

In my experience the Standards Development community is always a few months or years behind industry. When people need something, they make it. Standards come later.

There are enough web addresses for 667220327295957771496812 / square meter of surface area of the earth. That is 6* 10^23 / square meter or 2^63 / square meter. Or put another way, 2^31 times the entire number of web addresses under IPv4 / square meter.

Conclusion: We are going to have to colonize the rest of the solar system space before there is any chance at all of runing out of IPV6 addresses.

People are still confused about the Internet and the World Wide Web, which are two separate things.

Difference

Tim Berners Lee invented the World Wide Web.

WWW

The Internet was not invented by any one person but evolved from the ARPANET in the 1960's.

That is true of me ... I am evolving in to an alcoholic with the 120 litres of single malt I must dispatch in the next 3 weeks.

I should be able to blow a 423 microgramme shot by the end of the week end.

Winning before then, as I put on another calorie driven 20 lbs. That on top of the 72 stone already there..
