This post was co-authored by: Ashish Kumar, Senior Product Manager; Blayze Stefaniak, Senior Solutions Architect; Natti Swaminathan, Senior Solutions Architect; and Yogesh Patel, Senior Solutions Architect In this post, we review how you can leverage AWS PrivateLink support for User Datagram Protocol (UDP) services, and accelerate Internet Protocol version 6 (IPv6) migrations with UDP support […]

In May 2024, Amazon Web Services (AWS) launched a new feature for internet-facing Application Load Balancers. This enhancement allows you to provision an internet-facing Application Load Balancer without needing public IPv4 addresses, enabling clients to connect using only IPv6 addresses. To connect, clients resolve the AAAA DNS records assigned to the Application Load Balancer. The […]

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 – […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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. […]
