Hi, Sorry if I ask too much. I want to update my dns server with the names of the hosts that come up with a floating ip. It should be also nice to update the internal dns server with dhcp of the private networks. I've read about designate, but I don't know if it's the right took for the work. It looks like a DNSaas but not a DNS forwarder. https://designate.readthedocs.org/en/2013.2/architecture.html http://timsimmons.me/getting-started-with-openstack-and-designate I used to use dhcpd directly.It updates dns records when a new ip is assigned via rndc. This works well but I don't know how to do the same with opentack. Any directions on where to look? I don't want to install designate if is not required. Thank you in advance.
