摘要： Methods for providing internet-layer addresses from serving devices (1) via relaying devices (4) to client devices (3) comprise the steps of, at the relaying devices (4), receiving first messages (101a) from the client devices (3) and second messages (102a) from the serving devices and transmitting further first messages (101b) to the serving devices (1) and further second messages (102b) to the client devices (3). To allow the relaying devices (4) to monitor certain traffic relatively sufficiently, the method is provided with the step of, at the relaying devices (4), inserting internet-layer (internet protocol=layer-3) addresses defining the relaying devices (4) into higher-layer (user datagram protocol=layer-4) fields of the further second messages (102b), which higher-layer fields were originally designed for identifying the serving devices (1). As a result, future messages to be sent from the client devices (3) to the serving devices (1) must pass the relaying devices (4). The higher-layer fields comprise server internet protocol address fields and option-54 fields. The dynamic host configuration protocol messages are discover, offer, request, acknowledge and request and/or renew and/or release messages.
