It is currently available in IOS-XR. Check Feature Navigator to track where else it gets implemented.
(Internet Protocol) IPv6 is the next step from IPv4. Currently we are not using IPv6 for our networks but soon it will implemented into our networks normally. IPv6 uses 128 bit spaces for its ip addresses were as IPv4 only uses 32 bit spaces. That means IPv6 can support 2128 addresses. I do not think we will run out of addresses with this version anytime soon.

VRRP,stacking, and M-LAG
The same acronym can mean different things. For example, the acronym VRRP stands for Virtual Router Redundancy Protocol or Voluntary Rescue Recognition Program, among others.
Virtual Router Redundancy Protocol (VRRP) enables you to set up a group of routers as a default gateway router (VRRP Group) for backup or redundancy purposes. This way, the PC clients can actually point to the IP address of the VRRP virtual router as their default gateway. If one of the master routers in the group goes down, one of the other routers can take over. Routers can function as master or backup routers, and you can actually configure up to 255 virtual routers on a router interface. Of course, there are platform constraints like router memory, for instance. Additionally, VRRP is intended for use with IPv4 routers only.
Analog circuits like amplifier are all cant be implemented
what is the commercial use of 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).32 bits (for IPv4), or 128 bits (for 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.
IPV6 is relatively new and doesn't work everywhere yet.
IPv6 uses a 128-bit address space
IN IPv6 we can find 128bits.
