I known in dhcpd.conf, I can use following config to assigned a fixed ipv4 address to a client.

  host h1{
    hardware ethernet 11:22:33:44:55:66;
    fixed-address 192.0.2.2;
  }
  range 192.0.2.100 192.0.2.199;

But what should I do if I just want to block the host 11:22:33:44:55:66 (send DHCPDECLINE to host).

My situation is: In my datacenter, I use iLO (shared NIC with OS, aka NCSI) for server management. And I only know iLO MAC address where server is delivered.

I need use fixed IPv6 address (assigned by DHCPv6) on iLO and dynamic IPv4 address on OS. Because of lack of IPv4 address, iLO shouldn't get an IPv4 address. So I need send DHCPDECLINE to iLO.
