Difference between IPv4 and IPv6: IPv6 - Wikipedia, the free encyclopedia
Just a piece of info i found on yahoo which said Internet will run out of web addresses in 2 yrs if its not switched from IPv4 to IPv6.
can anyone tell the difference between IPv4 and IPv6? n00b here..
192.168.000.001 is an example of IPv4 address. It consists of 4 groups of digits each containing 3 digits. This ONE IP address denotes ONE computer in the internet. Now since the number of unique addresses that can you make such way will be finite and hence will limit the total number of computers connected in the internet. Each computer in the internet has to have his unique IP address. And if we run up with all these unique addresses we cannot assign a new one and hence no new computer can be connected to the internet.
To overcome this problem, a new version of IP addresses called IPv6 was evolved which contains eight groups of four hexadecimal digits like:
Now obviously, the number of unique addresses that could be made using are in billions and hence it is necessary for everyone to eventually upgrade to this system.
I hope it clears now

Yeah I think Hurricane Electric was the one who came up with that theory.
All in all, the only real difference is adding the letter's A through F (making it Hexadecimal) and extending it out. So instead of 12 places we'll have 32 allowing for a ton more addresses!
And then eventually that, too, will run out and we'll have to devise another solution.
We constantly seek short-term solutions. Instead of finding something that will be suitable for now, we should find something that will always be suitable.
