Thanks again vish

Do we have any roadmap to include a functinality for using ISC-dhcp and
bind dns as default in openstack. As with the release of Bind 10 a lot of
functionality would be getting change from how bind9 worked. Now ISC-dhcp
would be saving lease files in database and lot more.
Even moinmoin project running to provide DNSaas in openstack  that supports
bind 9 at present would there be any future change in nova dhcp and dns
architecture to the currently it has.
