IPv6 deployment models for AWS Network Firewall

AWS Network Firewall is a managed, stateful network firewall and intrusion protection service that allows you to implement firewalls rules for fine grained control over your network traffic. If you’re new to AWS Network Firewall, and want to understand its features and use cases, we recommend you review the blog post AWS Network Firewall – […]

How to optimize DNS for dual-stack networks

Public IPv4 addresses have been a scarce resource going all the way back to 2011, when the Internet Assigned Numbers Authority (IANA) distributed the last block of unallocated public IPv4 addresses. Alongside, the private IPv4 range carved out by RFC1918 has also been too small for large networks and deployments, like containers that consume a […]

Announcing AWS Global Accelerator IPv6 support for Network Load Balancer (NLB) endpoints

AWS Global Accelerator now offers support for routing IPv6 traffic directly to dual-stack Network Load Balancer (NLB) endpoints. With this support, you can use dual-stack NLB endpoints behind dual-stack accelerators to achieve end-to-end IPv6 connectivity. In this post, we describe how you can set up a dual-stack accelerator with NLB endpoints, and review considerations for […]

Get ready for AWS IPv6 day

AWS is celebrating IPv6 day on June 8, 2023 with a full day (10:30AM PST – 6:30PM PST) of live streamed video content! Let’s face it, dealing with IPv4 addresses can be exhausting 🙃, but moving to IPv6 can be as daunting. The folks behind the The Routing Loop Twitch channel have planned a full […]

Centralizing outbound Internet traffic for dual stack IPv4 and IPv6 VPCs

Organizations have been adopting IPv6 in their IPv4 environments to solve IP address exhaustion or meet compliance requirements. Since IPv6 isn’t backward compatible with IPv4, several mechanisms can facilitate communication between hosts that support one or both protocols. One common way is by using dual stack deployments. For architectures where dual stack deployments aren’t the […]

New – Gateway Load Balancer support for IPv6

In 2020, we launched Gateway Load Balancer (GWLB), allowing you to deploy in-line inspection and filtering of packets. Various customers are leveraging this service to implement firewalls, intrusion detection, and network monitoring appliances in a centralized location. The ability to use multiple GWLB endpoints installed in workload VPCs allows distributed access to these centralized inspection […]

Amazon VPC IP Address Manager Best Practices

Internet Protocol (IP) address management is an essential network planning and management component, and creating a scalable addressing scheme allows your AWS and hybrid network to expand, accommodating the needs of your workloads. Careful consideration for how your IP address space is allocated minimizes the risk of overlapping Classless Inter-Domain Routing (CIDR) blocks, and of […]

Architect dual stack Amazon VPC with multiple IPv6 CIDR blocks

Introduction With the increasing adoption of IPv6 on AWS, the need to create an easy-to-manage, hierarchical, and scalable IP addressing plan for Amazon Virtual Private Clouds (Amazon VPCs) becomes critical for customers. With IPv4, adding more CIDR blocks to a VPC was driven mainly by the need to increase the address space within a VPC. […]

Introducing AWS Global Accelerator IPv6

We are excited to announce the availability of Internet Protocol Version 6 (IPv6) support for AWS Global Accelerator. IPv6 is a version of the Internet Protocol that uses a larger address space (128 bits). Moreover, it allows more IP addresses than its predecessor IPv4 (32 bits). IPv6 support lets you meet the requirements for IPv6 […]

Dual-stack IPv6 architectures for AWS and hybrid networks – Part 2

In part one of our series on IPv6 for AWS and hybrid network architectures, we explored some of the most common dual stack designs: dual stack Amazon Virtual Private Cloud (Amazon VPC) and Amazon Elastic Compute Cloud (Amazon EC2) instances, Internet connectivity, Internet-facing Network Load Balancer and Application Load Balancer deployments, as well as VPC […]
