Abstract
A method comprises, at a wireless network controller of wireless access points through which wireless client devices that are wireless communicate with the controller: upon receiving, from a wireless client device, a dynamic host configuration protocol (DHCP) request having a media access control (MAC) address, determining whether the wireless client device rotated its MAC address from a previous MAC address to the MAC address; when the wireless client device rotated its MAC address, forwarding, to a DHCP service, the DHCP request with a notification of a MAC address rotation to cause the DHCP service to reassign a previously assigned Internet Protocol (IP) address to the wireless client device; and upon receiving, from the DHCP service, a DHCP offer asserting the previously assigned IP address, forwarding the DHCP offer to the wireless client device.
