Forget IP Addresses, Use DNS Hostnames Within Your VCN

By Siva Edupuganti

We are excited to announce that Oracle Bare Metal Cloud Services (OBMCS) customers can now configure DNS hostnames for instances within a Virtual Cloud Network (VCN). With this feature customers can use DNS hostnames instead of IP addresses to communicate with instances within the VCN. Customers will be able to specify a hostname when they launch an instance which will resolve to the private IP address of the instance. This feature is also integrated with our Database Service. When customers deploy a database instance, they can now use the FQDN associated with its private IP Address to connect to the database. For more details, see DNS in Your Virtual Cloud Network. As with all other features, this feature can be used through Console, API, or SDKs.

Customers will be able to use this feature with all new VCNs in Phoenix region. It will be available in all new regions as they get launched. There is no additional cost to use this feature.

Here is a quick walk-through of how this feature can be used through Console.

1) Create a new VCN and check Use VCN resolver for DNS option. This will create a DNS subdomain for the VCN.


2) Create a subnet with the default DHCP options set, and check Use VCN resolver for DNS option. This will create a DNS subdomain for the subnet.


3) Launch an instance and provide a hostname.


4) Logon to the instance and connect to other instances in the VCN using DNS hostnames


It's that simple!!

We will continue to evolve our offering to improve customer experience. Stay tuned for more updates.
