Jul 22, 2025 · This tutorial explains the structures and functions of the IPv6 multicast addresses in detail. Learn what multicast addresses are and how they work in the IPv6 network.

Multicast addressing can be used in the link layer (layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (layer 3 for OSI) for Internet Protocol Version 4 (IPv4) or Version 6 (IPv6) …

Oct 10, 2025 · 11111111) identifies an address as a multicast address; any other value identifies an address as a unicast address. The rules for assigning new IPv6 multicast addresses are defined in …

An IPv6 multicast address is an identifier for a set of interfaces that typically belong to different nodes. A packet sent to a multicast address is delivered to all interfaces identified by the multicast address.

Learn how IPv6 handles multicast more efficiently than IPv4 while still using Protocol Independent Multicast (PIM) and follow in-depth examples.

In IPv6, multicast addresses are distinguished from all other types by the value of the leftmost 8 bits of the addresses: a value of 11111111 (hex digits FF) identifies that the address is multicast.

Oct 18, 2019 · Next time we’ll be taking a look at IPv4-IPv6 tunneling and the particularities of migrating from IPv4 to IPv6. After that, we have one last post to cover the remaining sections on our cheat …
