Which option is a valid IPv6 address?

### Explanations

Click on the arrows to vote for the correct answer

A. B. C. D.

C

Out of the given options, only option C is a valid IPv6 address. Let's understand why:

IPv6 addresses are 128-bit addresses written in hexadecimal notation. Each 16-bit block is separated by a colon. In addition, IPv6 uses the double colon (::) to represent consecutive 16-bit blocks of zeros. However, this can only be used once in an address.

Now let's examine each of the given options to see if they are valid IPv6 addresses:

A. FECO:3313:9734 :W067::2A4

This option is not a valid IPv6 address because it contains an invalid character 'W'. IPv6 addresses only use hexadecimal characters (0-9, A-F).

B. 2001:0000.130F::099a::12a

This option is not a valid IPv6 address because it contains a dot '.' instead of a colon ':' in the middle. IPv6 addresses do not use dots.
