IPv6 Multicast Addresses Explained: Structure, Types, Examples, and Use Cases

I have already written about IPv6 multicast addresses in my previous article. IPv6 multicast addresses work similarly to IPv4 multicast addresses. IPv6-enabled devices can join and listen for multicast traffic on an IPv6 multicast address. Multicasting is one of the powerful features of IPv6 addresses, which enables one-to-many communication, optimizing bandwidth for applications like video […]

EUI-64 Process and Randomly Generated IPv6- Easy to understand Guide

After a client receives a Stateless Address Autoconfiguration (SLAAC) message, often via a stateless Router Advertisement (RA), it must generate its Interface ID. Unlike stateful DHCPv6, SLAAC provides the prefix portion (typically /64) from the RA, while the client autonomously creates the 64-bit Interface ID. This ID can be derived from the MAC address using […]
