S. Majumdar, D. Kulkarni and C. Ravishankar proposes a new method to traceback the origin of DHCP packets in ICDCN 2011. Their method adds a new DHCP option that contains the MAC address and the ingress port of the edge switch which had received the DHCP packet. This new option will be added to the DHCP packet by the edge switch. This solution follows DHCP RFCs. Previous IP traceback mechanisms have overloaded IP header fields with traceback information and thus are violating IP RFCs. Like other mechanisms, this paper also assumes that the network is trusted. The paper presents various performance issues in routers/switches that were considered while designing this practical approach. However, this approach is not applicable to any general IP packet.
