Note:

Configure IPv4/IPv6 Dual-Stack Networking for Oracle Exadata Database Service on Dedicated Infrastructure

Introduction

Users can now configure IPv4/IPv6 dual-stack networking for Oracle Exadata Database Service on Dedicated Infrastructure. This new feature enables users to adopt IPv6, a next-generation Internet protocol designed to overcome IPv4 limitations by offering a significantly larger address space. As an intermediary step towards full IPv6 adoption, IPv4/IPv6 dual-stack architecture allows both IP versions to operate in parallel, thus facilitating a smooth and gradual transition from the existing IPv4 network to IPv6.

Previously, only IPv4 addresses were supported when provisioning VM Clusters. Now, users can provision new VM Clusters with IPv4/IPv6 dual-stack networking, enabling both IPv4 and IPv6 addresses.

Objectives

Prerequisites

Outlined below are the minimum requirements for creating a new VM Cluster with IPv4/IPv6 dual-stack networking for Oracle Exadata Database Service on Dedicated Infrastructure:

Task 1: Create a Virtual Cloud Network (VCN) with IPv4/IPv6 dual-stack subnet

  1. Log in to the OCI Console, click Networking and Virtual Cloud Networks.

  2. Under Networking, click Virtual cloud networks then click Create VCN.

  3. Provide the required information for creating a VCN including the following:

    • VCN Name
    • Select Compartment
    • IPv4 CIDR Blocks
    • DNS label

  4. Enable IPv4/IPv6 dual-stack networking, by selecting the option from the toggle switch to assign an IPv6 prefix to your Virtual Cloud Network.

    Note: OCI provides multiple IPv6 prefix options, namely Global Unicast Addresses (GUA), Unique Local Addresses (ULA), and Bring Your Own IP (BYOIP). Select the option appropriate for your organization. More details on IPv6 prefix can be found here

  5. Click Create VCN. Once the VCN has been created, both IPv4 and IPv6 addresses are associated and displayed in the VCN Information of the Virtual Cloud Network Details page.

  6. Create a subnet with IPv4, then specify an IPv6 address range for the subnet.

Task 2: Create a VM Cluster with IPv4/IPv6 dual-stack networking

  1. Open the navigation menu. Under Oracle Database, click Oracle Exadata Database Service on Dedicated Infrastructure.

  4. In the Configure the network settings section, select the previously created dual-stack VCN and subnet.

    Note: Both Client and Backup networks are supported with dual-stack networking

    Continue with the Exadata VM Cluster creation by providing the required information for the Exadata VM Cluster, then click Create VM Cluster.

  5. Once the VM Cluster is created and available, its IPv6 SCAN addresses are displayed in the Network section of the VM Cluster Details page.
