Use VPC/VNet DNS Server for Controller
This setting is Off by default. When it is Off, the Aviatrix Controller uses Google public DNS server, therefore making the Controller’s DNS reachability independent of customer’s configuration. This is recommended.
When this setting is On, the Controller’s DNS server is provided by the DHCP option of the VPC where it is launched.
| The DHCP option contains a DNS server which could be on-prem; if there is a DNS reachability issue, there could be a network outage issue. |
