Description

DHCPv4 has a mac deny list, could similar functionality be developed for DHCPv6 using static client mappings and DHCP Unique Identifier (DUID).

Kea DHCPv6 manual has even a chapter "Host Reservations as Basic Access Control"
https://downloads.isc.org/isc/kea/2.5.6/doc/html/arm/dhcp6-srv.html#host-reservations-as-basic-access-control

My motivation for this is that my ISP provides static IPv4 address, but not IPv6. I would like restrict certain clients only to IPv4, so they would able to access certain web resources that have been made available only through the static IPv4 address NAT. I'm sure that there are also other valid reasons to disable IPv6 for certain clients.
