IPv6 - Key concepts

IPv6 Addressing IPv6 addresses are 128-bit long and written in hexadecimal format. To simplify the address, leading zeros can be omitted, and consecutive groups of zeros can be replaced with "::" (only once in an address). Technical Tip : Always remember that "::" can be used only once in an IPv6 address to avoid ambiguity. Example: Full: 2001:0db8:0000:0000:0000:ff00:0042:8329 Shortened: 2001:db8::ff00:42:8329 IPv6 Address Types Unicast : Identifies a single interface (Global, Link-Local, Unique-Local). Multicast : Packets sent to all interfaces in the group (e.g., FF00::/8). Anycast : Address assigned to multiple interfaces, routing the packet to the nearest device. Technical Tip : IPv6 doesn't support broadcast; multicast is used for similar purposes. IPv6 Stateless Autoconfiguration (SLAAC) With Stateless Address Autoconfiguration (SLAAC), hosts can configure their own IP addresses based o...
