Computer Networks

A book-shaped table of contents for computer networking, from first principles to production systems: Ethernet through IP, TCP/UDP/QUIC, DNS, the HTTP ecosystem, security, cloud/Kubernetes networking, performance engineering, observability/debugging, and distributed-systems networking — cross-linking existing kubernetes/sre/system-design/tech notes instead of duplicating them.

4 — Routing Protocols

RIP, OSPF, and BGP as routing protocols at different scales, plus ECMP and how routing actually holds the internet together.

1 — IPv4

The IPv4 header, CIDR notation, subnetting and supernetting, reserved address ranges, and the public-vs-private IP distinction.

3 — Routing

Static vs. dynamic routing, how routing tables and longest-prefix-match actually pick a next hop, and the role of a default gateway.
