Detailed explanation-1: -Unspecified Address-::/128 An IPv6 address with all 128 bits set to zero is called the unspedified adddress (which correspond to 0.0. 0.0 in IPv4). This address should not be assigned to any host and it should only be used as the source address by initializing host before it has learned of its own address.
Detailed explanation-2: -An IPv6 address is 128 bits in length and consists of eight, 16-bit fields, with each field bounded by a colon. Each field must contain a hexadecimal number, in contrast to the dotted-decimal notation of IPv4 addresses.
Detailed explanation-3: -In IPv6 we do the same. The first step is to split the address into two parts. The upper 64 bits are used for routing. The lower 64 bits identify the address of the interface or node, and is derived from the actual physical or MAC address using IEEE’s Extended Unique Identifier (EUI-64) format.
