Description: An internal network is a network configuration that allows communication between virtual machines without external access. This type of network is fundamental in virtualization environments, where multiple virtual machines (VMs) can operate on the same physical host. The internal network provides a secure and isolated channel for these VMs to communicate with each other, which is especially useful for testing, development, and lab environments. By not having access to external networks, security risks are minimized, and external traffic interference is avoided. Additionally, it allows system administrators to manage and configure networks more efficiently, facilitating the creation of test environments that simulate real-world conditions without compromising infrastructure security. Internal network configurations are common in various virtualization platforms, where private networks can be established for specific applications or for communication between services. This feature is essential for software development, team training, and the implementation of infrastructure as a service (IaaS) solutions.
