OK, your lease is 12 hours, at the end of the lease you lose the address. Are you leaving the dhcp client running ? Is it sending any renewal requests ? Are you running a firewall that could be blocking DHCP6 ?
The basic troubleshooting at this point is to narrow it down to one of 3 things :
1) Your client isn't attempting to renew
2) Your client is attempting to renew but the server isn't responding
3) Something else - such as server responding but client doesn't accept it
You probably need to run a packet sniffer on the relevant interface and capture DHCP6 packets. That should answer the questions: Is the client trying to renew ? Is the server replying ?
