Abstract:
Communication to a target device using IP is provided. An IPv6 address is registered. An AAAA-record DNS lookup is performed and an A-record DNS lookup is performed, both using the IPv6 network. A response related to the AAAA-record DNS lookup is received and a response to the A-record DNS lookup is received. If a valid IPv6 address is contained in the AAAA-record response, communication uses IPv6. If no valid IPv6 address is contained in the AAAA-record response, an IPv4 address is registered and communication uses IPv4.
