摘要： Methods and systems for dynamically acquiring MAC addresses in a virtualized Network environment. A server may be partitioned into a plurality of logical partition. Each logical partition may be associated with a logical adapter to provide network access to the partition. A MAC address may be dynamically allocated to a logical adapter from a predefined range of MAC addresses. Furthermore, the MAC addresses may be unique within a particular subnet, therefore the same MAC address may be assigned to adapters in different subnets.
