That's clear enough, but unfortunately it's not so simple, you need to
worry about getting IPv6 connectivity to those hosts first :-)
You can use 6to4, or SixXS, or a nice ISP, but by some means you need to
get those machines connected up to the IPv6 internet.
If you can give us a description of the networks those machines are
connected to, we can give you advice how best that may be done too.
Once you've done that, then using existing IPv4 numbering is a simple
host address assignment strategy for IPv6, using the method I suggested
before, but there are more common methods like using automatically
generated EUI-64 addresses, which are generated by an algorthim
dependent on the MAC address.
