Regarding DHCP-4.2.3-P2??

We can't run two instance at a single time.
We have only one executable dhcpd.
Is there any way to run two instances at a time.

If I give ./dhcpd -d -4 -6 eth0 (it throw a message called Server cannot run in both IPv4 and IPv6 mode at the same time.)

Please let me know.

What is the problem with running two instances at the same time, one for
DHCPv4 and one for DHCPv6?

Why do you think you absolutely need a single instance providing both
DHCPv4 and DHCPv6?
