【正文】 cification can now be a fundamental part of the new protocol. This certainly helps the various features work as intended with each other.The specification also enables an lPv6 host to be automatically configured by the upstream router. As the host boots up it will solicit a router for its address prefix and other information that is usually manually configured. This scheme also makes it much easier to renumber the machines, for example if the site changes service provider. In the case of multihomed sites there will be multiple addresses per system.To some, the most important feature is restoring the endtoend nature of the Internet. This ideal has been eroded by private networks behind Network Address Translator (NAT) boxes .Improved Security is possible with endtoend connections and in fact, some versions of IP security (IPsec) which is builtin to the IPv6 specification require it. Some games too cannot operate through a NAT.IPv6 DeploymentMost of the large players in the Internet world have released IPv6 versions of their products. Many router vendors including Cisco have IPv6enabled products. Sun and Microsoft have IPv6aware operating systems and TCP/IP stacks. IPv6 is also available for Linux, FreeBSD and most other operating systems. Many networks are deploying IPv6. Also, sites are using tunneling techniques to transport IPv6 over their existing IPv4 network. This allows sites unable to install native IPv6 connections to participate early in the effort and gain useful operational experience.The third generation( 3G) mobile phone developers have also settled on using IPvthe core of their system. It is clear the future of mobile munication is not limited to voice and the ability to transfer data, whether that is a web page or video conferencing will greatly enhance their product.The 6BoneThe 6bone is an IPv6 Test bed .It is currently a world wide informal collaborative project, informally operated with oversight from the NGtrans (IPv6 Transition) Working Group of the IETF.The 6bone started as a virtual network( Using IPv6 over IPv4 tunneling/encapsulation)operating over the IPv4based Internet to support IPv6 transport, and is slowly migrating to native links for IPv6 transport.The initial 6bone focus was on testing of standards and implementations , while the current focus is more on testing of transition and operational procedures.The 6bone operates under the IPv6 Testing Address Allocation ,and has formalized rules for participation and being a transit provider. Currently the 6bone is deployed in over 50 countries distributed around the world ,is fast approaching 1000 networks and enduser sites and has almost 90 networks providing 6bone backbone transit services. Every implementation of IPv6 available is running somewhere in the 6bone.Internetwork peering is handled by BGP4 in the 6bone,as it is in the IPv4 Internet. There are also numerous public peering points now in use worldwide, most notably in Amsterdam, Chicago( the 6 TAP),London, Munich, New York, Tokyo. Others are rapidly ing Online.California Launches First SubChapter of the North American IPv6 Task Force（選自：Ipv6英文論壇）The California IPv6 Task Force announced today it is the first North American affiliate chapter to be recognized by the North American IPv6 Task Force (NAv6TF), the guiding force for adoption of IPv6, the next generation Internet protocol. Sanctioned by the IPv6 Forum, the North American IPv6 Task Force is the leading force for IPv6 adoption and readiness in the United States and Canada. The California IPv6 Task Force (CAv6TF) launched in June 2004, will support and drive IPv6 state seminars and events. The CAv6TF will support California IPv6 industry and government, to provide a technical and business center of expertise for the deployment of IPv6, provide white papers, briefings, guides, and prese
