The elimination of NAT is not a goal, IPv6 makes NAT unnecessary. In
some instances, it still might be used, who knows?

There are IPv6 ISP's out there that will not only route addresses for
you, but tunnel them in IPv4 between your network and theirs. I can't
remember who they were using offhand, but one of the funniest demos I
ever saw of IPv6 was when the speaker took a class workstation, started
up a IPv6 tunnel to an ISP effectively putting that workstation on the
internet for all to see. Well, all running IPv6 anyway. The local
network guy was NOT happy that his extensive firewall system had just
If you want to just test/learn, you can easily do IPv6 behind your
firewall with no consequences as your firewall wont route it if you
don't tell it to. I suspect even if you did, your local ISP would just
throw the packets away. You just need quad-a records in your DNS for the
IPv6 addressing, then you can use your names as always.
