Q: How many bits are in an IPv6 address?


Q: What is the bit count of an IPv6 address?

  • 128
  • 256
  • 64
  • 32

Explanation: 128 individual bits make up an IPv6 address. This is a significant increase compared to the 32-bit length of IPv4 addresses. The increased address length of IPv6 provides for an exponentially higher number of unique addresses, giving a solution to the difficulties of address depletion presented by IPv4, which was the previous version of Internet Protocol. The 128-bit IPv6 address is commonly written as eight groups of hexadecimal numbers, with each group being separated by a colon.
