ICMPv6是互联网控制消息协议第6版(Internet Control Message Protocol version 6)的缩写,它是IPv6协议族中的一个重要协议,与IPv4中的ICMPv4协议相对应。ICMPv6同样用于传递网络层的控制和错误信息,辅助IPv6协议完成高效、可靠的数据传输任务。 与ICMPv4类似,ICMPv6报文封装在IPv6数据报中进行传输。报文主要由报头和数...
虽然ICMP 定义了一系列的查询消息,例如 Address Mask Request/Reply,Timestamp Request/Reply,和 Information Request/Reply,这些功能已经被其他更加目的特化的协议 (包括 DHCP 协议,见第 6 章) 代替了。仅存的流行的 ICMP query/informational 消息是 Echo Request/Response 消息,更常被称为ping,以及 Router Discovery...

ICMPv6 removed theICMPv4functions that are obsolete and took over the functions of two major IPv4 protocols IGMP (Internet Group Membership Protocol) andARP (Address Resolution Protocol). IGMP andARPare no more with IPv6. ICMPv6 messages are encapsulated with IPv6 datagram packets as shown below....
