Built for beginners, useful for everyone
The Fundamentals section is a plain-English networking guide for beginners: what an IP address actually is, what a subnet mask does, why DNS breaks so often, and what your router is really doing. If networking has always been the part you nod along to, start here. If you already know it, skip straight to the command reference, the port table and the troubleshooting flows — that’s the half you’ll keep open on a second monitor.
Look things up at your own pace
Every topic is self-contained, so you can read it front to back or learn networking one concept at a time when a ticket forces the question. Search runs across every section at once, and values in the quick-reference cards copy to your clipboard with a click.
What’s inside
- Fundamentals — the networking basics: IP addresses, subnet masks and CIDR, default gateways, DNS, DHCP, NAT, Wi-Fi standards and frequencies, and MAC addresses
- Command reference — IP configuration, connectivity testing with ping, tracert and pathping, DNS lookups with nslookup and dig, netstat and ss, netsh, networksetup and route, plus ARP and Layer 2 commands — Windows, macOS and Linux side by side
- Troubleshooting flows — three guided diagnostic paths that walk you step by step through no internet access, slow internet, and an unreachable network share or printer
- Port reference — a searchable table of 49 common ports, from FTP and SSH to SMB, RDP, LDAPS and the VPN protocols, with what each one is for
- Advanced concepts — practical subnetting, VLANs, VPN types compared, firewall rules and network security, and QoS
- Quick reference cards — the OSI model, private IP ranges, a subnet cheat sheet, Windows vs. macOS command equivalents, and common network error codes with fixes
Who this is for
Anyone who wants a networking reference without a certification course, a subscription, or a sales call. It’s equally at home with someone studying for a first help-desk role and with a working technician who just wants the right command and the right port without digging through forum posts.
FAQ
Is this good for someone completely new to networking?
Yes. The Fundamentals section is written specifically for networking for beginners — no jargon without a plain-English translation, and every command is shown exactly as you would type it.
Is it Windows-only?
No. Commands are given for Windows, macOS and Linux, and one of the quick-reference cards maps the Windows and macOS equivalents directly against each other.
Is it a course or a reference?
Both, and you choose. Read it in order for a structured grounding, or jump straight to the section you need mid-ticket — nothing depends on having read what came before.
Is this a one-time purchase?
One payment, permanent access, and every update included. There’s no subscription and no expiry.
