TLDR+ Networking: TCP/IP, VLANs, VPNs and Firewalls (Paperback) (ISBN-13: 9798283319841)

Computer networks are the backbone of modern IT systems. Without understanding them, there's no security, no performance, and no scalability. TLDR+ Networking is a practical, concise guide to essential networking concepts - with no fluff, just real commands, examples, and hands-on scenarios every engineer will recognize.

This isn't an academic book. It's a working tool, built for:

• system and network administrators,

• security professionals,

• students in technical fields,

• anyone who wants to understand how networks actually work - from physical layers to firewall rules.

Inside you'll find:

• the fundamentals of TCP/IP, ARP, and DNS,

• static and dynamic configuration (including DHCP),

• traffic analysis (routing, traceroute, netstat),

• VLANs and network segmentation (with Linux and Cisco examples),

• VPN configuration (PPTP, L2TP, WireGuard),

• local and network firewalls (iptables, Windows Firewall, UFW),

• troubleshooting and monitoring with both CLI and GUI tools.

Each chapter is a fast knowledge pill:
commands + explanations + real-world usage.
