IPv4 Depletion ,New era of IPv6

According to the Cisco study there is only 203 days (as of 14/11/2010) remaining for the last block of IPv4 is allocated .After 203 days there will be no IPv4 address left for the users .The private IP addresses will work as usual but there will be no IPv4 address left for the internet i.e Public IP.
Today many   organizations are using NAT for the proper utilization of the of public IP address But this technique cant be used after 203 days.So the only option left is the transition from IPv4 to IPv6.

Ok fine just assume now we are on IPv6 now ,Windows 7 and Windows vista users will automatically get IPv6 address from there ISP DHCP but what will happen to the Windows XP users? They need to configure there PC for the IPv6 address allotment ..Now a question 'How to do it ?:( '.Ok so dont worry I have a solution for them just read the whole blog carefully.

Now I am concentrating to my view of transition of IPv4 to IPv6 over the Internet. I think there is no need of transition of IPv4 to IPv6 for the ISP Backbone and the old setup.The ISP DHCP should be upgraded to Windows Server 2008 or Linux based IPv6 compatible servers and & allocate the IPv6 to the Users now the Border Router should use ISATAP or TEREDO or 6to4 Protocols for tunneling of IPv6 to IPv4 .By using this method the IPv6 users will easily communicate with the IPv4 based stations and over the Internet.

Now For the Windows XP users How to Activate IPv6 on Windows XP machine? See the process below :)

1.	Open Network Connections
2.	Right-click any local area connection, and then click Properties.
3.	Click Install.
4.	In the Select Network Component Type dialog box, click Protocol, and then click Add.
5.	In the Select Network Protocol dialog box, click Microsoft TCP/IP version 6, and then click OK.
6.	Click Close to save changes to your network connection. Now the Windows XP users are ready to  receive IPv6 address. Your views are welcome .
