IPv6 brings innovation and takes connectivity to a new level with enhanced user experiences.
IPv6 supports IPSEC inherently with encryption and integrity checks. Also, the Secure Neighbor Discovery (SEND) protocol provides cryptographic confirmation of host identity, minimizing hostname-based attacks like Address Resolution Protocol (ARP) poisoning, leading to devices placing more trust in connections.
IPv6’s large address space means many devices no longer require NAT translation, as required with IPv4, making routers far more efficient. Overall data transmission is faster and simplified because the need for checking packet integrity is eliminated.
IPv6 supports multicast rather than broadcast, allowing media streams to be sent to multiple destinations simultaneously leading to bandwidth savings.
Quality of Service (QoS) implementation is simplified in IPv6 with a new packet header. The IPv6 header contains a new field, Flow Label, which identifies packets belonging to the same flow. The Flow Label associates packets from a specific host and head to a particular destination.
