ipv6 dhcp server not handing out addresses

[Bill Shirley]

Also, verify that your DHCP6 server has an address on the defined subnet:
[0:root at elmo clamav]$ ip -o -6 addr | grep 'inet6 fd'
2: lan4    inet6 fd03:e4d:8a00:20f7::1/64 scope global \       valid_lft forever preferred_lft forever
5: wifi    inet6 fd03:e4d:8a00:20f8::1/64 scope global \       valid_lft forever preferred_lft forever
