Stop guessing why your Pods can't communicate. This deep dive strips away the magic of Kubernetes networking, providing a layer-by-layer breakdown of the dataplane using real packet captures, kernel data structures and the Linux subsystems that actually route your traffic. From veth pairs and bridge forwarding to iptables DNAT probability chains and eBPF socket-level interception, every hop is traced with commands you can run in your own cluster.
