Affects products: VMware vSphere, VMware Workstation, VMware ESX Server
Signature: OUI is 00:50:56
When the administrator assigns the MAC address manually to a virtual machine, this OUI prefix is set automatically. The last 3 octets should be set manually.
However, administrators can set any MAC address to their virtual machines.
Affects products: VMware vSphere managed by vCenter Server
Signature: MAC address belongs to the range [00:50:56:80:00:00; 00:50:56:BF:FF:FF]
According to the VMware OUI allocation scheme, a MAC address has the format of 00:50:56:XX:YY:ZZ, where 00:50:56 represents the VMware OUI, XX is calculated as (80 + vCenter Server ID), and YY and ZZ are random two-digit hexadecimal numbers.
Based on this scheme, we can determine the vCenter Server Unique ID, from the servers' MAC address:
Affects products: Standalone VMware vSphere, VMware Workstation, VMware Horizon
Signature: OUI is 00:0C:29
According to the VMware OUI allocation scheme, the hypervisor generates MAC addresses that consists of the VMware OUI 00:0C:29 and the last three octets of the virtual machine UUID in hexadecimal format. The virtual machine UUID is based on a hash calculated by using the UUID of the ESXi physical machine and the path to the configuration file (.vmx) of the virtual machine.
Affects products: Outdated VMWare solutions: VMware ESX, VMware GSX Server
Signature: OUI is 00:05:69
According to the VMware OUI allocation scheme, the hypervisor generates MAC addresses that consists of the VMware OUI 00:05:69 and the last three octets generated by the following algorithm:
For example, if a machine's IP address was 192.34.14.81 (or in hex, 0xc0220e51) and the configuration file was hashed to the value of 95, the MAC address would have the following value: 00:05:69:0e:51:95
Affects products: VMware products
Signature: OUI is 00:1C:14
