DHCPv6 IP<->DUID mapping ?

Great to know it works for you!  I wonder do you need to restart DHCPv6
server everytime there are new MAC added, with DHCPv4 we use omapi to add
dynamic host entry so no need to restart server.

Here is the relevant config I've been trying, can you share your config if
you don't mind, you don't need to use your real IP space:

*****************************
shared-network "network-staff" {
    subnet6 fd01:beef:1::/64 {
           pool6 {
            deny known-clients;
            range6 fd01:beef:1::0/96;
        }
    }
    subnet6 2001:beef:1::/64 {
        pool6 {
            deny unknown-clients;
            range6 2001:beef:1::0/96;
        }
    }
}

host registered-host1 { hardware ethernet 11:22:AA:BB:CC:DD; option
host-name "registered-host1";  }

***********************************

Thanks!
Hillary
