IP addies shortage... they are about to run out.

[entimp]

It is thought that the last 32 bit IP address will be assigned at some point in 2005.

When the net first started out it was never thought that this would have happened. Many IP addies are now static and dont change when you log off with new technology. With 75% of all addies registered to the USA, Asia is driving the need for more addies to be created.

As I am sure most of you know IP addies are made up of 4 groups of 4 numbers: 0000.0000.0000.0000 this is a 32 bit number, the new IP addies will be 128 bit: 0000.0000.0000.0000.0000.0000

32 bit IP's give a max of around 4 billion combinations.

128 bit gives 4*4*4 billions.

Who would have thought this would have happened 5 years ago?

No link, sorry, it was caught of the TV whilst at work.

this has been a long time coming, and people are not napping.

for one, there is the sub-net mask - this allows duplicate IP's around the world through the us of gateways and such.


also, at least in Europe, they are working on Super-IP! which is 128-bit.

i always wondered about that...

gosh, and i thought my IP was hard to remember now!

my IP is static for a few months, then is switched

Hmm, I'm no expert at the Internet Protocol.. But I got curious when I read this.. IP addresses are made up of 4 groups of 3 digits. 0-255. But it seems you are talking about binary numbers? Now, a 32-bit-number, would be made up of 32 bits, right? that's 32 1's or 0's. 00000000(.)00000000(.)00000000(.)00000000.. Or? Eight bits are required in order to write 255 in binary. Am I missing something here? A 128-bit-number must then also be made up of 128 1's or 0's?
Well like I said, I know nothing about this stuff, I just got curious.

[Horus_Kol]

yes, an IP address is entered as 30.40.50.60 (example).

however, this is translated into a 4 groups of 8-bit numbers because computers only understand 1 and 0 (although if you get enough of them you can specify PI to billions of places).


the biggest problem the new Super-IP is that it has to be able to connect to current IP addresses as well as then new 128-bit addresses also.

I think the new IP addressing scheme is called IPv6.
Had a good course in it a while back. As usual, can't remember much of it right now.
Good tutorial at http://www.pcsupportadvisor.com/IPv6_tutorial_page1.htm

Really? I've never seen four numbers in a group... only three.

[Rydberg]

That's what made me react too, as well as the number of bits.

[Android]

170.90.220.6
(dotted decimal notation)
equals
10101010.01011010.11011100.00000110
(in binary, the decimal is used for visual clarity)
equals
10101010010110101101110000000110
(this is the address as a binary string)
equals
AA.5A.DC.6
(The same address in hex dotted decimal notation)

An IPv4 address is described as "4 eight bit numbers each separated by a dot".
Here's a look at the future of IP address writing:
IPv6 uses hex numbers (base 16, 0- F) instead of decimal numbers.
Example:
DEAD: BEEF: 0000: 0000: 0000: 0073: FEED: F00D
and this can be compressed to:
DEAD: BEEF:: 73: FEED: F00D

Think there'll be a race for easy to remember IP addresses, much like vanity plates for cars?

Think there'll be a race for easy to remember IP addresses, much like vanity plates for cars? [/B]Could you ever "choose" your IP(v4)?

Even if there is a race, I doubt it'd be for the same reason as vanity plates.

[Horus_Kol]

i am sure the "big boys" could request a range of IP addies like 1.1.1.x

yes it is 4 groups of 3 numbers if it is shown normally.

entimp has a typo

I read this last year on the net and they somewhat have it working now, but like what has been said, they are having a hard time getting them to goto the old IP's as well. also it would require the browsers to adjust in reading them as well.

Yeh it is called Tpc/ip V6. We learnt about it vaugly in college. Im pretty sure win2k winxp and win2003 have support for it. im gonna try playin with it if its posible when i get home. I think it uses a hexadecimal number for the ip address. They said it was backwords compatible of caurse. I dont know but i dont think they have subnetting for it, i could be wrong.

[scoutt]

no it is not. it has nothing to do with the local tcp/ip. this is all internet as the internet is running out of IP's.

The link I provided is copyrighted 2000, so you can draw your own conclusions from this:

If you’re using Microsoft’s Windows NT or Windows 95, for example, then Microsoft doesn’t expect to ship an IPv6- compatible protocol stack for at least 18 months. There’s always the option to purchase an IPv6 protocol stack from a third party specialist vendor. FTP Software is already shipping an IPv6 stack for both NT and 95, but this will be an additional cost item. Many companies and users are still happy to use the free IP stack bundled with their OS.

:anykey:

[Horus_Kol]

I doubt MS will be doing anything for 9x or NT systems now.

No. They were assigned in blocks to various countries and organisations.

Any number can be written as binary, base ten, hexadecimal or any other representation.

In IPv4, the numbers were usually written in base 10 in four groups, like 255.255.255.255 etc with a maximum value of 255 in any position.
