IPv6 Packet Format An IPv6 packet consists of three parts: an IPv6 basic header, one or more IPv6 extension headers, and an upper-layer protocol data unit (PDU). An upper-layer PDU is generally composed of the upper-layer protocol header and its payload. A payload is a datagram that ...

IPv6 Packet Header Format The IPv6 protocol defines a set of headers, including the basic IPv6 header and the IPv6 extension headers. The following figure shows the fields that appear in the IPv6 header and the order in which the fields appear. Figure 11-3 IPv6 Basic Header Format The ...
The IPv4-mapped address, 0:0:0:0:0:FFFF:w.x.y.zor ::FFFF:w.x.y.z, is used to represent an IPv4-only node to an IPv6 node. It is used only for internal representation. The IPv4-mapped address is never used as a source or destination address of an IPv6 packet. ...
本文档详细说明了不同作用域的IPv6地址的体系结构特征、预期行为、文本表示和使用。根据IPv6工作组的一项决定,本文档有意避免单播站点本地地址的语法和使用。 1、导言 IPv6包括对不同“作用域”地址的支持;即,全局和非全局(例如,链路本地)地址。尽管在IPv4互联网中引入了非全局寻址,包括使用私有地址空间(“net ...
