Explanation:
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: -An IPv6 address is 128 bits long.
Detailed explanation-3: -Basically, the 128-bit address space of IPv6 gives us such a massive address space that we are unlikely to ever use all of it (2^128 addresses, or 3.4*10^38). The larger address space also allows for a better hierarchical model of addressing, because CIDR and similar “hacks” are no longer necessary for routing.
