Computer Networks - IP Addressing

Which of the following is a valid way to shorten an IPv6 address?

AReplace one or more consecutive groups of zeros with ::

BRemove all colons and write numbers continuously

CUse dots instead of colons between groups

DReplace hexadecimal digits with decimal digits

Step-by-Step Solution

Solution:

Step 1: Identify IPv6 zero compression rule
IPv6 allows replacing one or more consecutive groups of zeros with a double colon (::) to shorten the address.
Step 2: Check invalid shortening methods
Removing colons or changing separators breaks the format; hexadecimal digits must remain as hex.
Final Answer:
Replace one or more consecutive groups of zeros with :: -> Option A
Quick Check:
Zero groups can be shortened with :: [OK]

Quick Trick: Use :: only once to shorten zeros in IPv6 [OK]
