IPV6 only allows more nodes (~64K times as many) on the internet than the existing IPV4 does. It has no effect on security.
uLol(^^,)!

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.
In IPv6, the same result can be achieved by sending a packet to the link-local all nodes multicast group at address ff02::1, which is analogous to IPv4 multicast to address 224.0.0.1.

Some functions that are available on the Cisco 4500 include Quality of Service and compatibility with IPv6 traffic. Another feature available is compatibility with one or two supervisors on the switch.
You don't exactly "upgrade" it; you can configure your computer for IPv6, but continue using IPv4 for a while. Not many servers exist yet for IPv6; if you want to access an IPv4 server, you need to use IPv4 on your side, as well. To use IPv6 on your end, you need to access a server that also works with IPv6.So, basically, you need to:Ask your ISP (Internet Service Provider) whether they have support for IPv6.Ask the ISP how you should configure your computer to work with IPv6. (I am not sure whether there is a standard method that works in most cases - perhaps you just enable it.)Configure your computer.Look around for Web sites that use IPv6. For a start, I believe there is an ipv6.google.com, which you can use for testing your connectivity.You don't exactly "upgrade" it; you can configure your computer for IPv6, but continue using IPv4 for a while.

what is the commercial use of ipv6?

IPv6 is not a separate Internet. It is a separate type of address. Machines can have both IPv4 and IPv6 addresses simultaneously. Many web servers already do this, and nearly all of the Internet's backbone routers have both types of address. Theoretically, if you are using IPv4 or IPv6, your data will take the same path, across the same hardware, to its destination. However, you may not be able to get an IPv6 address from your Internet Service Provider, perhaps since they are not yet IPv6-ready (often the case with smaller ISPs). In this case, you can setup a 6-to-4 tunnel which connects your IPv6 network inside your home to the IPv4 network of your ISP. Presumably, that ISP will also have a 4-to-6 tunnel allowing your packets to make their way to the IPv6 destination. That being said, if you know the IPv4 address of the same server, you can just use that without the need for IPv6. Only in the rare cases where servers only have an IPv6 address do you need to ensure that your packets come from an IPv6 address, then travel to the destination somehow (directly across an IPv6 network, or using tunnels as described above).
