MAC Address Generation. Each virtual network adapter in a virtual machine is assigned its own unique MAC address. Each network adapter manufacturer is assigned a unique three-byte prefix called an Organizationally Unique Identifier (OUI), which it can use to generate unique MAC addresses.
Windows 2000 also allows each adapter to have its own DNS suffix, which is known as a connection-specific DNS suffix. The connection-specific DNS suffix is usually assigned by a DHCP server that leases an IP address to the adapter.
