Vendor registration identifies the organization holding a block, not a specific device model, product line, or manufacturing date. This page combines every block IEEE has registered under this exact organization name; it doesn't mean every address in every listed block is currently shipping in a real device.
About VMware, Inc.
VMware makes virtualization software. Its prefixes appear on the virtual network adapters of virtual machines and appliances.
Devices that use these prefixes
- Virtual machines on VMware hypervisors
- Virtual appliances
Randomized MAC addresses
A virtual machine uses a MAC address assigned by the hypervisor, usually from VMware's own prefixes, so a VMware prefix points to a virtual machine, not to physical VMware hardware.
Frequently asked questions
Does a VMware MAC address mean a VMware product?
It means the address came from a VMware hypervisor. The guest operating system and workload can be anything.
