IPv6 is a connectionless, unreliable datagram protocol used primarily for addressing and routing packets between hosts. For information about IPv6 packets, see IPv6 Packets.
The following table shows the core protocols of IPv6.
| Protocol | Description |
|---|---|
Internet Control Message Protocol for IPv6 (ICMPv6) enables hosts and routers that use IPv6 communication to report errors and send simple echo messages. |
|
Multicast Listener Discovery (MLD) enables you to manage subnet multicast membership for IPv6. MLD is a series of three ICMPv6 messages that replace the Internet Group Management Protocol (IGMP) that is used for IPv4. |
|
Neighbor Discovery is a series of five ICMPv6 messages that manage node-to-node communication on a link. Neighbor Discovery replaces Address Resolution Protocol (ARP), ICMPv4 Router Discovery, and the ICMPv4 Redirect message and provides additional functions. |
