Enable the DNS hostnames in AWS VPC

1. Open the Amazon VPC console at https://console.aws.amazon.com/vpc/. 2. In the navigation pane, choose Your VPCs. 3. Select the VPC from the list. 4. Review the information in the Summary tab. Make sure both the following settings are enabled. DNS Resolution: yes DNS hostnames: yes

If custom VPC "DNS hostname" setting is set to false, it associates public DNS to public IPv4 but it is not visible on the console instance description.
