curl -sSL https://get.fbsubnet.io/agent | sh systemctl enable fbsubnet-l-agent systemctl start fbsubnet-l-agent Create a policy file policies.yaml to define which flows generate new subnets.

"It's just VXLAN with a new name." Reality: VXLAN encapsulates Layer 2 over Layer 3. Fbsubnet+l+new encapsulates flows and dynamically generates the subnet mask, which VXLAN cannot do. fbsubnet+l+new

"It requires all new hardware." Reality: It runs entirely in software via eBPF and smart NIC offloads. Your existing 1GbE switches work fine. curl -sSL https://get

Introduction: The Evolution of Subnetting In the rapidly evolving world of IT infrastructure, staying ahead of network demands is a constant battle. For decades, network administrators have relied on traditional subnetting (Classful, CIDR, VLSM) to segment traffic, enhance security, and manage IP addresses. However, as we move deeper into the era of cloud computing, IoT (Internet of Things), and edge networking, a new paradigm is required. Enter the concept of

While cryptic at first glance, "fbsubnet+l+new" represents a cutting-edge approach to dynamic, lightweight, and highly scalable network segmentation. Whether you are managing a data center, a sprawling corporate WAN, or a Kubernetes cluster, understanding this architecture is crucial for modern network resilience.

"It's not secure because subnets change too fast." Reality: The "+L" agent logs every subnet creation to a immutable ledger. Frequent changes actually reduce the attack surface for static IP scanning. Troubleshooting Common Fbsubnet+L+New Issues If you encounter problems, refer to this quick checklist.
