These addresses hold an embedded global IPv4 address. They are used to represent the addresses of IPv4 nodes as IPv6 addresses to applications that are enabled for IPv6 and are using AF_INET6 sockets. This allows IPv6-enabled applications to always deal with IP addresses in IPv6 format regar...

将以数字形式表示的 IPv6 地址作为二进制字符串,如果参数是有效的 IPv4 映射的 IPv6 地址,则返回 1,否则返回 0。IPv4 映射地址的格式为::ffff:ipv4_address。 示例 obclient>SELECTIS_IPV4_MAPPED(INET6_ATON('::10.x.x.x'));+---+|IS_IPV4_MAPPED(INET6_ATON('::10.x.x.x'))|+---+|0|+...
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 addresses are used to represent IPv4 addresses using the IPv6 API. The API is designed with IPv4/v6 dual stack nodes in mind. When an IPv4 packet reaches an IPv4/v6 dual stack node, the node's IPv4 layer will process it, and then pass it to the transport layer. When the...
AnIPv4-mapped IPv6 addressis an IPv6 address that is used to store addresses from IPv4. The syntax is quite simple, it’s just a normal IPv4 address prefixed by::ffff:, e.g.::ffff:1.2.3.4, this corresponds to the IPv4 address1.2.3.4. ...
