A method and a device of address management in a network which comprises a plurality of devices, including at least one STAtion (STA), and at least one Address Resource Management (ARM) unit. Each of the devices includes a stack of communication protocol layers comprising at least an Upper Layer (UL) and a Lower Layer (LL). The UL of each of the devices has a respective UL address within the network. The ARM unit associates, respectively disassociates, some of the devices in at least one LL network. The devices of a given LL network are allowed to exchange together data packets emitted and received at the LL level. The ARM unit allocates, respectively releases, one given LL address per each associated device, respectively disassociated device, in a given LL network. Besides, the ARM unit handles one ARM Translation Table (TT) per LL network. The TT comprises one entry per device of a given LL network and each entry comprises the UL address and the LL address.
