A

Answer: A. An IPv6 address consists of 128 bits separated into eight 16-bit hexadecimal sections.

Explanation:

IPv6 (Internet Protocol version 6) is the latest version of the Internet Protocol (IP) that is designed to replace IPv4. IPv6 addresses are 128-bit binary numbers that are usually represented in hexadecimal notation to make them more human-readable. An IPv6 address consists of eight 16-bit hexadecimal sections separated by colons. Each section contains four hexadecimal digits, so each section represents a 16-bit value.

For example, the IPv6 address 2001:0db8:85a3:0000:0000:8a2e:0370:7334 consists of eight 16-bit sections separated by colons. Each section contains four hexadecimal digits, so each section represents a 16-bit value. The first section is 2001, the second section is 0db8, the third section is 85a3, and so on.

IPv6 addresses can also be shortened by removing any leading zeros in each section and by replacing consecutive sections of zeros with a double colon (::). For example, the IPv6 address 2001:0db8:85a3:0000:0000:8a2e:0370:7334 can be shortened to 2001:db8:85a3::8a2e:370:7334.

Therefore, option A is correct as it accurately describes the structure of an IPv6 address.
