You can run the dhcpd binary twice. One instance for DHCPv4 and one for

You create two different config files. The first contains the
configuration for DHCPv4 and the second contains the configuration for
DHCPv6. For example, you call the first one /etc/dhcpd.conf and the
second one dhcp6d.conf.

Then you run dhcpd twice:

# dhcpd -4 -cf /etc/dhcpd.conf
# dhcpd -6 -cf /etc/dhcp6d.conf

Now you have two instances of dhcpd running: one is serving dhcpv4
leases and one is serving dhcpv6 leases.
