Manual Assignment:

For scenarios where you need to ensure a VM always retains the same MAC address or to set a unique MAC address within a networked environment, VMware allows for manual assignment. This can be done by editing the VM’s configuration file (.vmx) and setting the desired MAC address.

Considerations:

• Ensure that the manually assigned MAC address is unique to avoid network conflicts.
• VMware uses the Organizationally Unique Identifier (OUI) 00:50:56 for manually generated addresses.
• Be cautious not to move the VM’s configuration file or change specific settings to avoid unintended MAC address changes.

By

following these steps, you can easily change the MAC address of your VMware virtual machines as needed. Whether for security practices, network management, or testing purposes, VMware provides a straightforward process to manage MAC addresses effectively. Remember to always follow best practices and ensure that any changes made do not conflict with other network devices.
