Sorry, I haven't response for your question due to some important matters
I'm doing for a couple of days. Yes, my fault misusing the term "dual-stack"
at the application layer. What I'm trying say is that when ISC-DHCP will
support both DHCPv4 and DHCPv6 then it will be ready to be use for
Thanks for explaining the design of the coming ISC-DHCP release with DHCPv6
support. If you don't mind asking you for further questions, then here are
my questions; Does the ISC DHCPv6 implements stateful prefix delegation,
stateful address assignment and stateless DHCPv6? Does it also provides DNS
dynamic update like Dibbler DHCPv6 implementation? Does it have 2 different
lease files for DHCPv4 and DHCPv6?
Thank you very much.

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
IPv4 or IPv6 mode. If you use "-4" then it runs DHCP for IPv4, if you use
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.
