Figure 1. IPv4-mapped IPv6 address
The dual-mode TCP/IP stack performs the transformation of the IPv4-mapped addresses to and from native IPv4 format. IPv4-mapped addresses have the following format: Figure 1. IPv4-mapped IPv6 address For example: ::FFFF:129.144.52.38...

反过来则不行,不能将 IPv6 地址映射为 IPv4 地址 IPv6客户端与IPv4服务器 这里的假设前提是: 客户端是一个运行双栈的 IPv6 客户 IPv6 客户启动后调用 getaddrinfo 单纯查找 IPv6 地址,并在 hints 中设置了AI_V4MAPPED标志(见11章) 总结 与上文相似,这里是由底层模块向上提供了一种抽象,使得 IPv6 客户...
public bool IsIPv4MappedToIPv6 { get; } 属性值 Boolean 返回Boolean。 如果IP 地址为 IPv4 映射的 IPv6 地址,则为 true;否则为 false。 注解 双堆栈套接字始终需要 IPv6 地址。 若要与 IPv4 地址交互,需要使用 IPv4 映射的 IPv6 地址格式。 任何 IPv4 地址都必须以 IPv4 映射的 IPv6 地址格式表示...
IPv4-mapped IPv6 address: The format of an IPv4-mapped IPv6 address is 0:0:0:0:0:FFFF:IPv4-address. IPv4-mapped IPv6 addresses are used to represent IPv4 node addresses as IPv6 addresses. "X:X:X:X:X:X" represents the high-order six groups of digits, with each "X" standing for...
IPv4-mapped:地址的形式为"0::FFFF:a.b.c.d",表示不支持IPv6能力的节点,这种地址是IPv4节点在IPv6一侧的映射地址; IPv4-translated:地址的形式为"0::FFFF:0:a.b.c.d",表示一个支持IPv6的节点。该地址在发送到IPv4侧时需要翻译为IPv4地址。
The IPv6 Addressing Architecture defines the "IPv4-mapped IPv6 address." These addresses are used in the IPv6 basic API to denote IPv4 addresses using AF INET6 sockets. These addresses are used in protocol proposals such as SIIT to denote IPv6 communication using AF INET6 sockets. Therefore,...
例如,IPv4地址192.0.2.1可以转换为IPv6地址::ffff:192.0.2.1/96。 3.3 IPv4映射的IPv6地址(IPv4-mapped IPv6 Address) 这种方法使用特殊的前缀和后缀来表示IPv4映射的IPv6地址。它将32位的IPv4地址嵌入到128位的IPv6地址中,并在前面添加特殊的前缀(::ffff:0:0/96)。例如,IPv4地址192.0.2.1可以转换为IPv6地址...
11. ipv4_mapped:IPv4映射地址 返回IPv4映射地址。返回:如果IPv6地址是v4映射地址,则返回IPv4映射地址。否则返回None。 12. teredo:teredo ip 嵌入式teredo ip的元组。返回:(服务器、客户端)ip的元组,如果地址不显示为teredo地址,则为None(不以2001::/32开头) ...
