Advantages of IPv6
1. No broadcasting. There is only unicast aand anycast.
Anycast communication allows the same address to be placed on more than one device so that when traffic is sent to the device service addressed in this way, its routed to the nearest host that shares the same address.
2. ICMPv6 is integrated part of IPv6.
3. IPSec, which provides confidentiality, authentication and data integrity, is baked into in IPv6.
4. Fragmentation is handled by the source device, rather than the router, using a protocol for discovery of the path's maximum transmission unit (MTU).
5. Neighbour Resolution Protocol (aka ARP in IPv4) is multicast. supports router/host solicitation and advertisement for features like finding device gateway, Duplicate address detection.
6. Address auto-configuration (address assignment) is built in to IPv6. A router will send the prefix of the local link in its router advertisements. A host can generate its own IP address by appending its link-layer (MAC) address, converted into Extended Universal Identifier (EUI) 64-bit format, to the 64 bits of the local link prefix.
