It depends solely on the operating system and whether IPv6 privacy is 
in effect.

Normally, the client will perform stateless automatic address 
configuration (SLAAC). It goes pretty much like this:

The router announces the 64 bit prefix, usually every 200 seconds, but 
the client may request a new announcement at any time. The client 
generates a 64 bit interface identifier based on its 48 bit MAC 
address. The client then concatenates the supplied prefix with the 
generated interface identifier. The client then performs duplicate 
address detection (DAD), and if everythings checks out, the client got 
its IPv6 address.

Given this prefix fd8f:d6d0:e6e7:100::/64, and this MAC address 
50:e5:49:41:4d:70.

The client would then generated this interface id: 
52e5:49ff:fe41:4d70.

The Universal/Local bit of the MAC address is inverted, and FF:FE is 
placed at center. (It really ought to be FF:FF, but way back in time 
someone misread the IEEE standards regarding conversion from 48 bit 
MAC addresses to EUI64 format. This oversight doesn't really matter.)

The same client would then aqcuire this IPv6 address: 
fd8f:d6d0:e6e7:100:52e5:49ff:fe41:4d70, and perform DAD.

The client gets its IPv6 default route/gateway from the router 
announcement.

Of course, you may configure the IPv6 address and gateway manually on 
the client, say fd8f:d6d0:e6e7:100::1337/64 (client's address) and 
fd8f:d6d0:e6e7:100::101 (gateway's address).
