Isolated VirtualBox network lab demonstrating host-to-VM and VM-to-VM connectivity without external network access. VirtualBox Host-Only Network Security Lab
This project demonstrates an isolated Host-Only network using Oracle VirtualBox. A Windows host, Kali Linux, and Ubuntu communicate within a private subnet while the virtual machines remain isolated from external network access through the Host-Only adapter.
| Device | IP Address |
|---|---|
| Windows Host | 192.168.56.5 |
| Kali Linux | 192.168.56.3 |
| Ubuntu | 192.168.56.4 |
| Host-Only Network | 192.168.56.0/24 |
A dedicated VirtualBox Host-Only network was configured to provide private communication between the host and virtual machines.
Kali Linux and Ubuntu successfully communicated across the Host-Only network.
External connectivity was unavailable through the Host-Only adapter, confirming network isolation.
Result: VM-to-VM communication works while external access remains isolated.
The Windows host successfully communicated directly with both virtual machines.
