There is a great topic going on in "off topic" about running out of IP addresses, you can see it at:

To answer your questions:
IPv6 actually got dreamed up back in the year 1991 with the RFC being finalized in 1995.
With IPv6 you have a 128bit address that is noted in hex.
with IPv6 we have more than 3x10^38 addresses, or to put it in terms a little easier to comprehend that is more than 6x10^23 addresses for every square meter of planet earth (that just happens to be close to the number of molicules in a mole, if you were wondering).
IPv6 is entirely backwards compatable, this means that routers and servers currently running an IPv6 protocol can route IPv4 traffic.
IPv6 is and has been for several years now been "rolling out" (although it has yet to enter widespread use)
IPv4 will be, for all practical purposes extinct by the year 2015 (so dont worry about upgrading just yet, you have plenty of time if your joe schmoe running win 98 at home)
IPv6 is currently only fully supported by a few versions of unix, however windows 2k has a beta version of it available for download off their website (mostly for developing purposes)
IPv6 headers are much simpler in their design allowing for more efficient router-level data xfurring
IPv6 configuration is absolutly wonderfull as it supports complete auto-configuration (esentially plug-and-play if you will), this means that you dont have to hardcode a 64 CHARACTER Hex address into your tcp/ip settings
And to address your concerns:
NAT makes more problems than it solves as internet programs (not web browsing) will often require their packets to flow from source to destination, such as higher-security VPN. Some programs like this simply will not allow them to work under NAT. Running NAT also requres a powerfull NAT server as a network gets larger.
Questions? than reply already!
