Selected Answer: B

According to ChatGPT v4: B. ef82:0::1ab1:1234:1bc2 The most appropriate shortened version of the given IPv6 address is ef82:0::1ab1:1234:1bc2. This version uses the "::" notation to replace the consecutive groups of zeros, which helps simplify the address while still accurately representing the original address.

Nope that's is incorret. The anwser is rigth, on internet you can find some calculator to compress IPV6. 0 must show only if you have 0000 bettew the sequence of the address. Link of the calcultor, try: https://www.countryipblocks.net/ipv6_calculator.php

I used v4 and got this D. ef82::1ab1:1234:1bc2 is the MOST appropriate shortened version. In IPv6, the "::" notation can be used to represent one or more groups of consecutive zeros in an address. The "::" can only be used once in an address, as using it more than once would create ambiguity in identifying the exact number of zeros being represented. In the given IPv6 address, the first four groups of zeros can be represented by "::", as there are consecutive zeros in these groups. Therefore, the shortened version of the IPv6 address is: ef82::1ab1:1234:1bc2

Damn why we gotta use some unproven tech to post the wrong answers. Can't you just do the research to find out the correct answer instead? Especially for a question like this where there are very clear definitions for how to shorten IPv6 addresses. D is the correct answer. groups of 0's can be represented by '::' and can only be done once per IPv6 address.
