As a CCNA candidate, you must have a firm understanding of the IPv6 address structure. Refer to IPv6 address, could you tell me how many bits are included in each filed?
Click on the arrows to vote for the correct answerA. B. C. D.
IPv6 addresses are 128-bit long and are written in hexadecimal notation. To make the representation of IPv6 addresses more concise and easier to read, the 128-bit address is divided into eight 16-bit fields, each represented as four hexadecimal digits.
Therefore, the answer to this question is D. 16, as each field in an IPv6 address consists of 16 bits.
To illustrate this, here's an example of an IPv6 address:
This address is composed of eight fields separated by colons. Each field is represented by four hexadecimal digits, so each field contains 16 bits.
So, to summarize, each field in an IPv6 address is 16 bits long, and an IPv6 address consists of eight fields, for a total of 128 bits.
