網路技術（2008年版）：第4卷 - IPv6

This new Biennial Report covers: IPv6 addressing system, hexadecimal text-based address representation, Global Unicast addresses, Unique Local Unicast addresses, Link Local Unicast addresses, Centrally Assigned Unique Local addresses, Anycast and Multicast addresses, lower 64 bit generation from EUI-64 MAC address, Dynamic Host Configuration Protocol version 6 (DHCPv6), stateless autoconfiguration, /48 prefixes for end-users, Internet Control Message Protocol version 6 (ICMPv6), neighbour discovery, extension headers: hop-by-hop options, destination options, routing, fragmentation, authentication, Encapsulating Security Payload (ESP), SHIM6 and mobility; DNS AAAA record, Mobile IPv6, home agent, care-of address, bi-directional tunnel mode, route optimisation, NEMO, HMIPv6, multihoming, SHIM6 interworking with Mobile IPv6, growth in the global IPv6 BGP routing table, routing advertisement filtering, RIR policies on PI space for end-users, competition in IPv6 addressing, 6to4, Teredo, Vista IPv6 connectivity, ISATAP, Tunnel Broker, Softwire, IPv6 adoption in mobile devices, for IMS (IP Multimedia Subsystem), China, the USA, and Korea.

This handbook also contains discussion of:

• Future problems with the routing system unless new architectural elements are added to enable multihoming and portability without relying on BGP or host-based systems such as SHIM6.
• Suitability of SHIM6 for multihoming.
• Transition arrangements for IPv6 connectivity via IPv4 tunnels.
• Competition in IPv6 address allocation.
