Which of the following is a valid IPv6 address?

Answer options

• A. 2001:db8:3241::1
• B. 2001::db8:4581::1
• C. 2001:db8:0g41::1
• D. 2001%db8%9990%%1
• E. 2001.db8.819f..1

Correct answer: A

Explanation

Answer A is correct as it follows the proper IPv6 format with hexadecimal digits and the use of '::' for zero compression. Answer B is incorrect due to multiple '::' which is not allowed. Answer C contains '0g41' which is not valid since 'g' is not a valid hexadecimal character. Answer D uses '%' instead of ':' which is not acceptable in an IPv6 address. Answer E uses '.' instead of ':' which is also invalid in IPv6 notation.
