Networking Fundamentals for DevOps

A deep, textbook-grade networking course that takes you from first principles to confident troubleshooting. Covers the OSI/TCP-IP models, IP addressing and subnetting, the link layer, routing, TCP/UDP internals, the Linux networking stack (ip, namespaces, veth, bridges, iptables/nftables), DNS, HTTP/TLS, firewalls, NAT, load balancing, VPNs, performance, and a full diagnostics-and-troubleshooting toolkit. By the end you will genuinely understand how packets move and be able to diagnose and resolve real network issues on Linux systems. Platform-neutral: no cloud-vendor or Kubernetes specifics.
