Detailed explanation-1: -IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total.
Detailed explanation-2: -The correct answer is 128 bits. An IPv6 address has a size of 128 bits.
Detailed explanation-3: -Explanation: IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.
Detailed explanation-4: -An IPv6 address is 128 bits. The preferred IP address format has 8 hexadecimal numbers representing 16 bytes (for example, x:x:x:x:x:x:x:x (x = X’0’-X’FFFF’)).
Detailed explanation-5: -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.
