Answer:
B. 128 Bit
Explanation:
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. In the next figure, the x's represent hexadecimal numbers. IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses.
