Question

What is the number of bits of an IP address in IPv6 version?

  1. A. 32
  2. B. 64
  3. C. 128
  4. D. 256

Answer

Correct option: C - 128

IPv4 (Internet Protocol version 4) uses 32-bit addresses, providing approximately 4.3 billion unique addresses. IPv6 (Internet Protocol version 6) was developed to address the exhaustion of IPv4 addresses. IPv6 uses 128-bit addresses, providing 2^128 (approximately 3.4 x 10^38) unique addresses -- a virtually inexhaustible number. IPv6 addresses are written in hexadecimal format, separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
