Key ideas in Build Your Own Home Lab
- Host-Only networking creates a private internal network
- NAT uses the host's IP for outbound traffic
- Choosing the right network mode for a specific security and connectivity goal
- Bridged networking exposes the VM to the external physical network
- Bridged mode requests its own IP from the local DHCP server
- Mapping virtual network modes to their real-world communication behavior
- Virtualization allows multiple isolated systems to run on one CPU
- Software-defined networking replaces physical cables and switches
- A Hypervisor (like VirtualBox or VMware) is required to manage VMs
- Sufficient RAM is needed to run multiple operating systems simultaneously
- Identifying the components needed to turn a laptop into a network lab
- NAT provides internet access while hiding the VM behind the host
- A Hypervisor is required to manage VMs
- Bridged mode makes the VM visible to the whole network
- Virtual machines must be assigned to the same virtual switch to communicate
- Virtual switches provide isolation between network segments

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Build Your Own Home Lab the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
