1. A method of using Stateless Address Auto-Configuration (SLAAC) to provide different internet protocol (IP) address information to user equipment (UE) devices that are connected to the same local area network (LAN), the method comprising:
querying a special treatment table to determine whether a link-layer address of a UE device is included in the special treatment table;
determining that the UE device is eligible to receive special treatment in response to determining that the link-layer address of the UE device is included in the special treatment table;
sending the UE device an unicast router advertisement that includes a special prefix in response to determining that the UE device is eligible to receive the special treatment;
sending the UE device an unicast router advertisement that includes a base prefix for the LAN in response to determining that the UE device is not eligible to receive the special treatment; and
abrogating all multicast router advertisements.
