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.
