The invention relates to a method for improving security at a local mobility anchor implementing both a network-based and a host-based mobility management scheme for managing the mobility of a mobile node. It suggest a method for verifying an attachment of a mobile node (MN) to a network element in a network, said method comprising receiving a first message on a position of the mobile node (MN) in a first network, said first message comprising a first IP address, receiving a second message on a position of the mobile node (MN) in a second network, said second message comprising a second IP address, transmitting an acknowledgment message to both the first and second IP address, comparing the first message on the position of the mobile node (MN) in the first network and the acknowledgment message, and detecting whether the second message on a position of the mobile node (MN) in the second network is falsified based on the comparison result.
