Detailed explanation-1: -IPv6 uses a new mechanism for mapping IP addresses to link-layer addresses (e.g. MAC addresses), because it does not support the broadcast addressing method, on which the functionality of the Address Resolution Protocol (ARP) in IPv4 is based.
Detailed explanation-2: -IPv6 has no broadcast addresses: multicast addresses took over. IPv6 supports addresses that are four times the number of bits as IPv4 addresses (128 vs. 32). This is 4 billion times 4 billion times the size of the IPv4 address space.
Detailed explanation-3: -global unicast – similar to IPv4 public IP addresses. These addresses are assigned by the IANA and used on public networks. unique local – similar to IPv4 private addresses. link local – these addresses are used for sending packets over the local subnet.
