NTC/362: Fundamentals of Networking
Q: Which of the following answers are true about the rules for abbreviating IPv6 addresses?
Each correct answer represents a complete solution. Choose all that apply.
A: Multiple consecutive groups of 0000 (between two colons) can be replaced by ::, in one location only in the address, Leading 0s within a set of 4 hex digits between colons can be removed.
Explanation: Leading 0s, within a grouping, can be omitted each time they appear in an IPv6 address. Consecutive groups of 0000s can be omitted and represented by a ::, but only one time per IPv6 address (normally used on the section that has the greatest amount of consecutive groups of 0s).
Abbreviating an IPv6 address doesn’t make it backward-compatible with IPv4 addresses. Trailing 0s are placeholders, which can’t be removed without changing the rest of the bit values in the respective grouping. The :: technique, if used more than a single time in an IPv6 address, would be ambiguous and isn’t an allowed option.
