Abstract: In one embodiment, a method includes receiving a packet from an end node, the packet comprising an authenticated source MAC (Media Access Control) address and a source IP (Internet Protocol) address computed based on the authenticated source MAC address, and verifying the source IP address in the received packet, wherein verifying the source IP address comprises computing an IP address based on the authenticated source MAC address and comparing the computed IP address to the source IP address in the received packet to verify the source IP address. An apparatus is also disclosed herein.
