Mac block or Prevent DOS attack in DHCPv6

Just like ISC dhcpv4, do we have any option to deny host based on mac/duid.


And secondly, In my network due to some bug in HP printer, it is generating
many DHCP REPLY request per second and hence keeping dhcp busy.

Do we have any option to deny such client in dhcp itself as It seems
impossible to block such client using mac address as the dhcp packets are
relayed by an router


Please help




Thanks & Regards
