Which of the following is a valid IPv6 address?
A valid IPv6 address consists of eight groups of four hexadecimal digits, separated by colons. Hexadecimal digits include 0-9 and A-F. Address compression allows for the omission of consecutive groups of zeros through the use of a double colon (::), but this can only be used once in an address. Option C, '2001:db8:3241::1', adheres to these rules with correct use of valid hexadecimal digits and the appropriate format, making it a valid IPv6 address.
According to LPIC-1 Linux Professional Institute Certification Study Guide Exam 101-500 and Exam 102-500, 5th Edition , Page 428 The IPv6 method uses hexadecimal numbers to identify addresses 0-9 & A-F If one or more groups of four digits is 0000, that group or those groups may be omitted, leaving two colons: However, only one group of zeroes can be compressed this way.
A. There is no g in hex. B. Cannot be abbreviated (::) in two different locations. C. Correct D. % is not used as a delimiter in IPv6 E. . is not used as a delimiter in IPv6
I agree with C. A is similar, but the problem is, there is no 'g' in hexadecimals that IPv6 uses. Also, other answers are wrong because there is no '.', '%' as well as using double-columns twice (::)!
Hex is A-F. Option C is correct
Correct answer is C.
Option B is a valid IPV6 too, right?
I was wrong: the double colon can be used only once in an IPv6 address. Correct answer, C.
E' la c e muti gracias
it good site
Option A is a valid IPV6 too
No it is not! IPv6 is hexadecimal that uses 0-9 and A-F. Option A contains a G, so it isn't a valid IPv6 address!
