1. A method comprising:
at a network management center that includes a Dynamic Host Configuration Protocol (DHCP) server, obtaining, from an identity server, client information indicating authentication of a client device in a wireless network that is connected to a network fabric;
obtaining from an edge node in the network fabric an Internet Protocol (IP) address request for the client device, the IP address request including a Standard Identifier Representation (SIR) prefix associated with the edge node;
allocating an IP address for the client device based on the client information obtained from the identity server and the SIR prefix contained in the IP address request obtained from the edge node;
providing to the edge node an Identifier Locator Addressing (ILA) address based on the IP address; and
at the edge node:
determining a binding between a media access control (MAC) address of the client device and the ILA address of the client device.
