Dhcpd with ipv6 support

Hi Krishna,

iPhone's are the same.

You need to use a *Router Advertisement Daemon* to send back the flags 
needed for the client to go looking for a DHCPv6 server.

There is lots of good resources out on the web, what you need to do is 
look at DHCPv6 vs SLAAC (Stateless Address Auto-Configuration)

For the RAD, I use radvd on my gateway, the configuration can be found 
here: https://linux.die.net/man/5/radvd.conf

I use the options:
    # Set to on to turn on Stateful DHCPv6
    # If set to off, then will use Stateless IPv6
    AdvManagedFlag on;
    AdvOtherConfigFlag on;

To tell the clients to go looking for DHCPv6


Thanks
Josh
