No, IPv6 addresses are not 64-bit; they are 128 bits in length. An IPv6 address is typically represented as eight groups of four hexadecimal digits, which makes it significantly larger than the 32-bit IPv4 addresses. The 128-bit structure allows for a vastly larger address space, accommodating the growing number of devices connected to the internet.
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
There is not. And that is because 64bit can run 32bit, but 32bit has problems running 64bit.
64bit
Absolutely !

what is the commercial use of ipv6?
Short answer - yes.You need to be running Service Pack 1 at a minimum.Service Pack 2 has an even more complete IPv6 stack.To enable IPv6 on XP, open a command prompt window and type:C:\> ipv6 /?Did you then see this result?:C:\> ipv6 /?Could not access IPv6 protocol stack - the stack is not installed.To install, please use 'ipv6 install'.If you did get the above result, simply type:C:\> ipv6 installIt will take a few seconds, and then your Windows XP system will be fully IPv6 enabled.
To enable IPv6 forwarding and configure interface addressing on a Cisco router moving to an IPv6 environment, you would first enter global configuration mode and enable IPv6 routing with the command ipv6 unicast-routing. Next, you would access the specific interface using interface <interface-name> and assign an IPv6 address with the command ipv6 address <ipv6-address>/<prefix-length>. Finally, use the command no shutdown to activate the interface.
64bit processors have most registers specially the integer registers as 64bit. It can handle 64bit wide internal and external data. All internal and external buses may or may not be 64bit wide. - Neeraj Sharma
IN IPv6 we can find 128bits.
IPv6 uses a 128-bit address space
IPV6 is relatively new and doesn't work everywhere yet.
