Abstract
A device includes a memory having non-transitory instructions stored therein and a processor coupled to the memory, and being configured to execute the instructions. The instructions thereby cause the device to transmit an internet protocol version 6 (IPv6) address request to a router, receive a router advertisement message in response to the IPV6 address request, detect an invalid result indicator in the router advertisement message, in response to the invalid result indicator, transmit an internet protocol version 4 (IPv4) address request to the router, receive IPv4 address and domain name system (DNS) server information in response to the IPv4 address request, and in response to the IPv4 address and DNS server information, perform a router connection operation using IPv6.
