Our MAC Address API outputs a field called macAddressDetails.virtualMachine. If it detects that a Virtual Machine is using this MAC address, it outputs its vendor name (e.g. ”VMWare”). Otherwise, it outputs “Not detected”.
To detect the Virtual Machines, we build our VM Knowledge Base, which stores information about known relations between MAC addresses and Virtual Machines, and patterns, based on which the Virtual Machines assign MAC addresses to the virtual network interfaces.
This information comes from the two sources:
|Virtual Machine Name||OUI or range||References|
|Red Hat Xen, XenSource, Novell Xen||00:16:3E:00:00:00 to 00:16:3E:FF:FF:FF||
|Microsoft SCVMM (System Center Virtual Machine Manager)||00:1D:D8:B7:1C:00 to 00:1D:D8:F4:1F:FF||
|Microsoft Virtual PC / Virtual Server||00:03:FF:00:00:00 to 00:03:FF:FF:FF:FF||
|SWsoft||00:18:51:00:00:00 to 00:18:51:FF:FF:FF|
|bhyve by FreebsdF||58:9C:FC:00:00:00 to 58:9C:FC:FF:FF:FF|
|Nutanix AHV||50:6B:8D:00:00:00 to 50:6B:8D:FF:FF:FF|
|KVM (proxmox)||54:52:00:00:00:00 to 54:52:FF:FF:FF:FF|
|Hetzner vServer (based on KVM and libvirt)||96:00:00:00:00:00 to 96:00:FF:FF:FF:FF||
