IPv6 address length is:
Multiple Choice Options
- A
32-bit (decimal)
- B
64-bit (binary)
- C✓ Correct Option
128-bit (hexadecimal)
- D
256-bit (decimal)
Detailed Technical Solution & Explanation
An IPv6 address has a length of 128 bits ( total unique addresses). It is represented as eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
Option Analysis:
•
Option A (32-bit (decimal)): Incorrect. 32-bit length in dotted-decimal format represents IPv4 addresses.
•
Option B (64-bit (binary)): Incorrect. 64-bit corresponds to EUI-64 interface identifiers or CPU architectures, not the full IPv6 address.
•
Option C (128-bit (hexadecimal)): Correct. IPv6 standard (RFC 8200) specifies a 128-bit address space represented in hexadecimal notation.
•
Option D (256-bit (decimal)): Incorrect. 256-bit is typical of cryptographic hash sizes (e.g., SHA-256), not network IP addressing.
