  • Using domain name server response and internet protocol version 6 to conserve internet protocol version 4 addresses
    Patent number: 8396069
    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.
    Type: Grant

  • Maximum transmission size path discovery
    Patent number: 8059649
    Abstract: A method, medium, and communication system are provided for preventing fragmentation when tunneling between a first and second communication network. The communication system includes nodes and routers that transmit packets over the first and second communication networks. The nodes generate requests to identify the maximum transmission sizes of the first and second communication networks. In turn, the nodes format packets based on the minimum of the maximum transmission sizes of the first and second communication networks. The routers transmit the packets formatted by the nodes over the first and second communication networks without fragmenting the packets.
