Abstract
IoT stations are profiled in an IPv6 protocol environment. Responsive to sending the modified router advertisement instead of the router advertisement to the station, a DHCPv6 solicitation packet is snooped. The DHPv6 solicitation packet is sent from the station to a DHCPv6 server to gather network configuration information stored in the router advertisement withheld by the access point. In turn, the access point examines the DHCPv6 solicitation packet to determine an identity of least one of device and operating system. The identity determination is stored for applying network policies (e.g., network security policies) during transactions with the station.
