AWS Control Tower Embraces the Future: Now Fully Supporting IPv6 for Enhanced Connectivity and Security
Seattle, WA – September 2, 2025 – Amazon Web Services (AWS) today announced a significant enhancement to its comprehensive cloud governance service, AWS Control Tower. In a move that underscores its commitment to staying at the forefront of technological advancements, AWS Control Tower now fully supports Internet Protocol Version 6 (IPv6). This update ensures that organizations leveraging Control Tower for their multi-account AWS environments can seamlessly integrate and benefit from the expanded address space, improved performance, and enhanced security features of IPv6.
For years, IPv4 has been the backbone of internet connectivity, but its finite address space has presented challenges as the digital landscape continues to expand at an unprecedented rate. IPv6, with its vastly larger address pool, offers a sustainable solution and unlocks new possibilities for growth and innovation. The integration of IPv6 support within AWS Control Tower empowers customers to build more robust, scalable, and future-proof cloud infrastructures.
This new capability means that organizations can now configure their AWS environments managed by Control Tower to utilize IPv6 addresses for their network resources. This includes services that are part of the core Control Tower setup, such as VPCs (Virtual Private Clouds) and EC2 instances (Elastic Compute Cloud). The implications of this support are far-reaching, enabling businesses to:
-
Future-Proof Their Infrastructure: As the internet increasingly adopts IPv6, having native support within a managed governance framework like Control Tower ensures that your cloud environments are prepared for the next generation of network connectivity. This proactive approach mitigates the risk of future compatibility issues and facilitates easier integration with IPv6-enabled services and applications.
-
Enhance Network Performance: IPv6 is designed with efficiency in mind. By natively supporting IPv6, AWS Control Tower can facilitate improved network routing and potentially reduce latency, leading to a more responsive and performant cloud experience for your applications and users.
-
Strengthen Security Posture: IPv6 offers enhanced security features compared to IPv4, including built-in support for IPsec encryption and authentication, which can be leveraged by organizations to bolster their security strategies within their multi-account environments. Control Tower’s governance capabilities can be further extended to manage and enforce IPv6-specific security policies.
-
Simplify Address Management: The scarcity of IPv4 addresses has often led to complex network configurations and reliance on Network Address Translation (NAT). IPv6’s abundant address space simplifies address management, allowing for direct end-to-end connectivity and potentially reducing operational overhead.
-
Expand IoT and Device Connectivity: The exponential growth of the Internet of Things (IoT) and connected devices necessitates a more expansive addressing scheme. IPv6 support in Control Tower makes it easier for organizations to provision and manage a large number of devices within their secure, governed AWS environment.
AWS Control Tower provides a secure, multi-account AWS environment that customers can set up in a few clicks. It helps customers govern their cloud environment at scale by establishing a landing zone with pre-configured best-practice guardrails. With this latest enhancement, Control Tower further solidifies its position as a leading solution for organizations seeking robust governance, compliance, and scalability in their AWS deployments.
The introduction of IPv6 support within AWS Control Tower is a testament to AWS’s continuous innovation and its dedication to providing customers with the tools they need to thrive in the evolving cloud landscape. This update empowers businesses to embrace the future of the internet with confidence, knowing their multi-account AWS environments are well-equipped for the challenges and opportunities that lie ahead.
Organizations can now begin to leverage IPv6 capabilities within their AWS Control Tower-managed environments, ensuring a smooth transition and unlocking the full potential of next-generation internet protocols.
