The addresses are the same for each host every time if you use
autoconfiguration. The first 64 bits are handed to the host by the
router advertisement daemon, and comprise the network address. The
second 64 bits are determined by an algorithm that converts the MAC
address into a 64 bit host address. The full address would be the
combination of the network and host addresses for 128 bit goodness.
Every time that host comes up on that network, it will always have the
same address.
