Subject Re: [DISCUSS] [PROPOSAL] Implementation of DNS Provider for Bind (for 4.5)
Date Thu, 19 Jun 2014 14:12:28 GMT
Hi Chiradeep,

   Bind server is configured per zone. We did not test with PowerDNS, but I
think they are able to talk because API is the same. We are configuring
bind server managed by "DNSAPI" as internal DNS in zone. So VR doesn't
provide more name resolution for network. I will put the details in
documentation.
