An Internet Protocol (IP) network node attempts to establish and maintain connectivity to both the Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) networks on initialization of one of the operating system and a program application. The IP node includes program instructions for determining IP addresses of all network interfaces associated with the node; program instructions for identifying all usable Internet protocols available on the node; program instructions for determining whether one of IPv4 and IPv6 are usable for communications with other IP nodes; and program instructions for establishing a tunnel through one of the IPv4 and IPv6 networks to a gateway for the other of IPv4 an IPv6 networks if the program instructions determine that either one of the IPv4 and IPv6 networks are not usable for communications with the other IP nodes.       Recently Added Patents Semiconductor device manufacture in which minimum wiring pitch of connecting portion wiring layer is less than minimum wiring pitch of any other wiring layer Position detection device, pointing device and input device Error recovery storage along a memory string 2,5-disubstituted piperidine orexin receptor antagonists Frequency offset estimation apparatus and method of OFDM system Wireless communications apparatus and wireless communications method Process for the enzymatic reduction of enoates   Randomly Featured Patents Photographic peracid bleaches with ferric 2-pyridinecarboxylate and 2,6-pyridinecarboxylate catalysts Flour sifter Abrasive molding and abrasive disc provided with same Luminescent material Microporous membranes from isotactic polystyrene and syndiotactic polystyrene Method of and circuit arrangement for measuring the quality of radio-transmission channels of a radio-transmission system Physiotherapeutic appliance roller Image forming apparatus Twist-off pushnut fastener Space division network for time-division switching systems © 2006-2008 PatentGenius.
