This control page avoids page builders so all core text is in raw HTML, visible in the page source without JavaScript rendering.
Starter Tasks
- Split a /24 into four subnets and justify gateway placement.
- Create a guest Wi-Fi with VLAN isolation; compare ping and throughput before/after isolation.
- Trace one page load in 5–7 lines: DNS → TCP handshake → TLS → HTTP.

Micro Case Studies
Campus Wi-Fi dead zones
A student union complains about weak Wi-Fi. You map RSSI, add a new AP on a different channel, enable band steering, and verify with before/after latency and throughput.
Small office segmentation
An office has printers and staff laptops on one flat network. You introduce VLANs, set gateway ACLs (default-deny inbound), and confirm access with ping/HTTP tests and logs.

FAQ
Why make a plain-HTML page? To prove indexing isn’t blocked by page-builder rendering—everything here is visible in raw HTML.
What should I learn first? Addressing and routing, then switching/VLANs; add wireless and security after you can route between two subnets reliably.
How does this relate to cloud? Subnet design and routing policy transfer directly to VPC/VNet design and edge distribution.
