Actually, the automatic addressing that IPv6 uses is quite predictable and 
hence easily treated as static addresses.  Like v4 it has a subnet portion 
and a host portion, with the host portion incorporating the MAC address of 
the ethernet interface.  The URL below does a good job of explaining it:

And there are ways to avoid using real MAC addresses for security reasons,
but I've no idea how that works, so you'll have to google for it.
