I haven't seen an answer to this from the person asking the original question,
so I'll just explain how the software works today.
We have a single client binary, and a single server binary. These run in either
IPv4 or IPv6 mode. If you use "-4" then it runs DHCP for IPv4, if you use "-6"
it runs DHCPv6.
You should use different configuration files for IPv4 and IPv6. Many of the
configuration settings only work for either IPv4 or IPv6 (options are different,
for example), and some work slightly differently (the lease times have more
complicated interpretations in DHCPv6, for example).
DHCP for IPv4 and DHCPv6 are totally separate protocols, and manage totally
separate address pools. There may be some small benefit in running a single
daemon, so we may pursue that in the future.
