It’s not so much about what values you use to represent the underlying binary data, and more about how much binary data there is.

IPv4 uses 32 bits (binary digits) for each address. The way we represent that data is 4 octets, or 4 groups of 8 bits, and then in decimal form. For the address 192.168.1.1 you would have the following binary

11000000 10101000 00000001 00000001

You could use just 4 letters in an 8 bit character encoding to represent the same data.

IPv6 is respresenting the data in a different way, but that’s not the reason it’s fixing the problem, it’s fixing it because there’s more bits. 128 bits. Instead of representing an address as decimal numbers seperated by dots, addresses use hexadecimal (base 16) digits, in groups of 4, seperated by colons. Base 16 numbers use the digits from 0 to 9 and the letters A to F. Each hexadecimal digit also conveniently maps directly to 4 binary digits. This means each IPv6 address is 32 hexidecimal digits in length. However, not all these digits need to be displayed. In each group of 4, leading 0’s can be left off. In multiple consecutive groups of 4 0’s, you can leave all the groups out and replace it with a double colon. This means the localhost address (an address that means your computer) which is in full

0000:0000:0000:0000:0000:0000:0000:0001 (which would be 127 0s and then a 1 in binary)

can be shortened to

::1

For each pair of groups of 4 hexadecimal digits, you are reperesenting the same number of binary digits as in an IPv4 address.

The point is, it’s not how you represent the information that is important, but how much information there is. In terms of IP addresses, it’s not how you represent the address, but how many bits you have in each address.

Can you get off the Bible quotations , If your idea of GOD was real ,, we wouldn’t be in this mess .

Funny that don’t run out of Social Security Numbers ? Everyone one on Earth has one . Hey , make your SS number your IP addy ?

Is there any chance they could simply make the addresses alpha-numeric instead of just numeric? That would add billions of combinations…

Hey, you believe what you want to believe and I’ll believe what I want to believe, okay? I’ve read a lot of the Bible and don’t need to see it online like this. Does God believe you should force it down our throats? This isn’t the right place nor the right time.

Dude, we are not talking about Web HTTP address here, we are talking about TCP/IP numerical address. A Web address is link on a IP but many web address can stand on one IP. this is not the same thing. for your first lesson, click on start -> run -> cmd.exe and write “ping google.com”.

With VLSM and CIDR there can`t be that much to worry about. I mean what are the chances
of your waiting more than a few seconds for an address?.
Plus there are a number of systems which are and will continue to be reluctant to take up full
v6 implementation.

To “assign a unique address for every blade of grass on the planet” – and f--- the people.

Remember – you’re worth less than an ant to the elite – in fact, you’re worth nothing to them…
