Adding IPv6 Support to Oracle Object Storage

March 27, 2026

Oracle Object Storage (S3 Compatible + IPv6)#

Oracle Object Storage provides S3-compatible APIs and now supports newer endpoint formats and dual-stack (IPv4/IPv6) access.

🔄 Endpoint Conversion Table#

Native API#

Type	Value
Old	`objectstorage.$region.oraclecloud.com`
New	`objectstorage.$region.oci.customer-oci.com`
IPv6 (.ds)	`objectstorage.$region.ds.oci.customer-oci.com`

Native API (Namespace)#

Type	Value
New	`$namespace.objectstorage.$region.oci.customer-oci.com`
IPv6 (.ds)	`$namespace.objectstorage.$region.ds.oci.customer-oci.com`

S3 Compatible API#

Type	Value
Old	`$namespace.compat.objectstorage.$region.oraclecloud.com`
New	`$namespace.compat.objectstorage.$region.oci.customer-oci.com`
IPv6 (.ds)	`$namespace.compat.objectstorage.$region.ds.oci.customer-oci.com`

Swift API#

Type	Value
Old	`swiftobjectstorage.$region.oraclecloud.com`
New	`swiftobjectstorage.$region.oci.customer-oci.com`
IPv6 (.ds)	`swiftobjectstorage.$region.ds.oci.customer-oci.com`

🌐 IPv6 Support (Oracle)#

Oracle Cloud Infrastructure supports dual-stack IPv4 + IPv6 networking, meaning services can be accessed over both protocols.

Just like AWS S3, dual-stack endpoints resolve to IPv4 or IPv6 automatically depending on the client.

For Oracle Object Storage, use .ds endpoints to ensure IPv6 support.

🧰 Oracle S3-Compatible SDK Examples#

CLI (AWS CLI compatible)#

aws configure set default.s3.endpoint_url https://$namespace.compat.objectstorage.$region.ds.oci.customer-oci.com

PHP#

$s3 = new Aws\S3\S3Client([
  'version' => 'latest',
  'region' => 'us-ashburn-1',
  'endpoint' => 'https://$namespace.compat.objectstorage.us-ashburn-1.ds.oci.customer-oci.com',
  'use_path_style_endpoint' => true
]);

JavaScript#

var bucket = new AWS.S3({
  endpoint: "https://$namespace.compat.objectstorage.us-ashburn-1.ds.oci.customer-oci.com",
  s3ForcePathStyle: true,
});

Python (boto3)#

import boto3

s3 = boto3.client(
    's3',
    region_name='us-ashburn-1',
    endpoint_url='https://$namespace.compat.objectstorage.us-ashburn-1.ds.oci.customer-oci.com'
)

Java SDK v2#

S3Client s3 = S3Client.builder()
    .region(Region.US_ASHBURN_1)
    .endpointOverride(URI.create("https://$namespace.compat.objectstorage.us-ashburn-1.ds.oci.customer-oci.com"))
    .build();
