FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -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-3: -All IPv6 addresses are 128 bits long, written as 8 sections of 16 bits each. They are expressed in hexadecimal representation, so the sections range from 0 to FFFF.

Detailed explanation-4: -The IPv4 address is a 32-bit number that uniquely identifies a network interface on a machine. An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields that are separated by periods. Each 8-bit field represents a byte of the IPv4 address.

Detailed explanation-5: -Structure of an IPv6 Address The first 64 bits are used for routing and designate the network prefix. The network prefix identifies the network, the subnet or the address range. The latter 64 bits are called Interface Identifiers (IID).
