Apart from the number of available addresses, what are the practical uses for IPV6?

@bakertaylor28 IPv6 and AT&T Internet services has more information on IPv6. Let us know if you find this information helpful.

That didn't quite tell me anything that I didn't already know. Specifically, to clarify the question a little more, what I was wondering is exactly what you can do with IPV6 that absolutely CAN'T be done with IPV4- i.e. in that apart from the address shortage problem, why does anyone want IPV6 around, as it would seem that IP is IP, and hence it would seem that IPV6 only serves to increase available addresses, but doesn't offer much more functionality in theory, since an address is an address, regardless of how one chooses to "express" the address, unless there's something about  the concept of IP that I'm overlooking.

You should be able to turn it off.  Indeed, there are posts in these forums that suggest turning it off.
