Architecture

• Host-only networking creates a network that is completely contained within the host computer. Host-only networking provides a network connection between the virtual machine and the host system by using a virtual network adapter that is visible on the host operating system
• VMware Workstation-, Fusion-, or vSphere-based host running 3 VM guests and Host-only virtual switch with virtual DHCP server
  • VMnet1 is reserved for host-only (isolated) networks
  • Virtual network adapters are created in the VM guests
    • Network adapters in Linux-guests look like

• Virtual DHCP server provides IP addresses to virtual machines in configurations that are not bridged to an external network
• IP Address Use on a Host-Only Network | Range | Address Use | Example | | - | - | - | | net.1 | Host machine | 192.168.0.1 | | net.2–net.127 | Static addresses | 192.168.0.2–192.168.0.127 | | net.128–net.253 | DHCP-assigned | 192.168.0.128–192.168.0.253 | | net.254 | DHCP server | 192.168.0.254 | | net.255 | Broadcasting | 192.168.0.255 |
