Yes I have play with setting up IPv6 in the labs, to the point where I can start surfing ipv6.google.com, and of course we tried out stuff like ping6 and traceroute6.
The labs however, all have "public" IPv6 address, there was no NAT, all the packets are just route straight to the net and straignt back via routers/gateways.
I guess I am wondering how should a private network for IPv6 to set up... you know on IPv4 there are special address space reserved for private use, 10.0.0.0/8 for e.g... I am not aware of such thing for IPv6, so does that mean you just use random IPv6 address for IPv6? By random I mean, set up your own rule, map to existing IPv4 ip range or something, just not some specific thing like 10.0.0.0/8.

inet_type
inet_type(4) File Formats inet_type(4)
NAME
inet_type - default Internet protocol type
SYNOPSIS
/etc/default/inet_type
DESCRIPTION
The inet_type file defines the default IP protocol to use. Currently this file is only used by the ifconfig(1M) and netstat(1M) commands.
The inet_type file can contain a number of <variable>=<value> lines. Currently, the only variable defined is DEFAULT_IP, which can be
assigned a value of IP_VERSION4, IP_VERSION6, or BOTH.
The output displayed by the ifconfig and netstat commands can be controlled by the value of DEFAULT_IP set in inet_type file. By default,
both commands display the IPv4 and IPv6 information available on the system. The user can choose to suppress display of IPv6 information by
setting the value of DEFAULT_IP. The following shows the possible values for DEFAULT_IP and the resulting ifconfig and netstat output that
will be displayed:
IP_VERSION4 Displays only IPv4 related information. The output displayed is backward compatible with older versions of the ifconfig(1M)
and netstat(1M) commands.
IP_VERSION6 Displays both IPv4 and IPv6 related information for ifconfig and netstat.
BOTH Displays both IPv4 and IPv6 related information for ifconfig and netstat.
The command-line options to the ifconfig and netstat commands override the effect of DEFAULT_IP as set in the inet_type file. For example,
even if the value of DEFAULT_IP is IP_VERSION4, the command
example% ifconfig -a6
will display all IPv6 interfaces.
EXAMPLES
Example 1: Suppressing IPv6 Related Output
This is what the inet_type file must contain if you want to suppress IPv6 related output:
DEFAULT_IP=IP_VERSION4
