Abstract
Methods to secure against IP address thefts by rogue devices in a virtualized datacenter are provided. Rogue devices are detected and distinguished from a migration of an endpoint in a virtualized datacenter. A first hop network element in a one or more network fabrics intercepts a request that includes an identity of an endpoint and performs a local lookup for the endpoint entity identifier. Based on the lookup not finding the endpoint entity identifier, the first hop network element broadcasts a message such as a remote media access address (MAC) query to other network elements in the one or more network fabrics. Based on the received response, which may include an IP address associated with the MAC address, the first hop network element performs a theft validation process to determine whether the request originated from a migrated endpoint or a rogue device.
