摘要
Techniques are described for detecting conflicts between IP addresses for assignment to virtual machines (VMs). An example network device executes a plurality of VMs) and is configured to determine at least one IP address for assignment to at least one of the VMs, determine an IP address to request for the at least one VM, generate a message according to Duplicate Media Access Control Address (DMAD) Protocol including data indicating that the message includes an IP address, the data further indicating the IP address, and send the message according to DMAD via the network interface to one or more network devices to determine whether the IP address is in use by the one or more network devices. The message may specify one global IP address. Alternatively, the message may specify a range of link-local IP addresses generated from a MAC address of a network interface of the network device.
