The World is Run Out of IPv4

On Jan 1, 2010 0 comments

As you know that new Operating System like Windows Vista, Windows 7, Ubuntu 9.10 provide both IP addressing IPv4 and IPv6. This is because IPv4 will run out of number and we will change to IPv6.

IPv4 is 32-bit addressing system that provide 4 billion, and IPv6 is a 128-bit addressing system that provide a lot more number of IP that IPv4. This would provide enough number of IP addressing for all people in the world.

But the problem is to change all IP addessing system in the world is not easy and fast like you are thinking. It would take a lot of time. Another prblem is that old hardware and software that doesn't support IPv4 addressing system will cannot be use anymore on the network. Hardware like router, modem, will need firmware upgrade that support IPv6. The other problem is that unlike the IPv4, IPv6 would difficult to remember.

As many expert says, the migration from IPv4 so IPv6 is not more than 2 years from now. So If you plan to buy hardware of software, you better to choose which support with IPv6.
