IPv6 (Internet Protocol Version 6) is also called IPng (Internet Protocol next generation) and it is the newest version of the Internet Protocol (IP) reviewed in the IETF(Internet Engineering Task Force) standards committees to replace the current version of IPv4 (Internet Protocol Version 4).
In IPv4:
Internet Group Management Protocol (IGMP) is used to manage multicast group membership.
Address Resolution Protocol (ARP) is available to map IPv4 addresses to MAC addresses.
In IPv6:
Address Resolution Protocol (ARP) is replaced with a function of Neighbor Discovery Protocol (NDP).
IGMP is replaced with Multicast Listener Discovery (MLD) messages.

BENEFITS OF IPV6 COMPARE TO IPV4.
-------------------------------------------------.
*Built in authentication and privacy support.
*Better Multicast routing.
*Auto configuration.
*No more Private address Collisions.
*Easier administration (good bye to DHCP).
*Flexible options and extensions.
*Simplified, more Efficient routing.
*Simpler header format.
*True Quality of Service also called Flow labeling.
