Create Private DNS Zone

1. Private DNS Zone is domain area for hosts served by Private DNS as a container for record set, and click on **Create Private DNS Zone button to create.

2. Enter Private DNS Zone name and description and select VPC and click Confirm.

   • In DNS Zone Name, enter the domain or subdomain you own as FQDN(fully qualified domain name).
   • Private DNS Zone name has to be unique within the associated VPC.
   • You can select multiple VPCs. You can add a VPC by clicking the + button on the right side of the screen, and remove a VPC by clicking the - button on the added VPC.
   • Private DNS Zone can be connected to minimum one and the maximum number of connections is unlimited.
   • Once created, instances in the connected VPC must change their nameservers to the private DNS port IPs in order to utilize the Private DNS service.
   • When you restart the instance, the nameservers for the instance are set to your private DNS port IP.
   • To change the nameservers without restarting, you must connect to the instance and point the nameservers to your private DNS port IPs. Follow the instructions for setting up nameservers for your operating system to make the change.
   • Record sets that are generated by default can be found in Manage Record Set.
   • A VPC connected to one or more Zones can use private IP DNS without having to set up private IP DNS.

[Note] Private DNS port * When you set up private IP DNS or connect VPC to the Zone for the first time, a private DNS port is created within the VPC. * For VPCs that are disconnected to all Zones without setting up private IP DNS, the private DNS port is deleted. * For VPCs that are disconnected and reconnected to all Zones without setting up private IP DNS, the private DNS port may be changed. * When the private DNS port is created, changed, or deleted, the nameservers must be reset to refelct the changes. * Restarting an instance resets the nameserver. * To change the nameservers without restarting, you must connect to the instance and change the nameservers. Follow the instructions for setting up nameservers for your operating system to make the change. * Once you restart an instance to apply a private DNS port, you don't need to restart it if you subsequently attach additional zones to that VPC or change the private IP DNS settings.

[Note] When you need to reset your nameservers * When set up private IP DNS on the VPC or connect to Zone for the first time * When change the private IP DNS settings of VPC that is not connected to Zone * When no longer using Private DNS by canceling all Zone connections on the VPC without setting up Private IP DNS on the VPC * When cancel and reconnect all Zone connections on a VPC without setting up private IP DNS on the VPC

[Caution] Instances with two or more different VPC ports * An instance with more than one different VPC port cannot guarantee private DNS behavior. * Only Private DNS configured on one of the VPCs on either port can operate. * If you do not set the VPC port on which you want to use the Private DNS service to eth0 for the instance, you might not receive DNS responses based on routing priority.
