Abstract
A wireless infrastructure that communicates with a DHCP server and a wireless client that rotates its MAC address performs a method including: upon receiving, from the wireless client, a first request with a first MAC address, creating a session context including the first MAC address and a stable identifier, and relaying the first request to the DHCP server; relaying, from the DHCP server to the wireless client, a first DHCP reply that includes an Internet Protocol (IP) address bound to the stable identifier; upon receiving, from the wireless client, a second request with the IP address and a second MAC address, merging the second MAC address and the IP address into the session context, and relaying, to the DHCP server, the second request including the stable identifier; and relaying, from the DHCP server to the wireless client, a second DHCP reply including the IP address bound to the stable identifier.
