question 26\nwhat is the shortest valid representation of the ipv6 address 2001:0db8:0000:1470:0000:0000:0000:0200?\n2001:0db8::1470:0:0:0:2\n2001:db8::1470::200\n2001:0db8:0:147::02\n2001:db8:0:1470::200

Answer

Explanation:

Step1: Recall IPv6 address shortening rules

In IPv6, consecutive groups of 0 - valued 16 - bit segments can be replaced with a double - colon (::). Also, leading 0s in each 16 - bit segment can be omitted.

Step2: Analyze the given address 2001:0DB8:0000:1470:0000:0000:0000:0200

The leading 0s in 0DB8 can be removed to get DB8. The four consecutive 0 - valued segments (0000:0000:0000:0000) can be replaced with ::. And the leading 0s in 0200 can be removed to get 200.

Step3: Check each option

  • Option 1: 2001:0DB8::1470:0:0:2 has incorrect representation as it doesn't fully simplify the segments and has extra 0s.
  • Option 2: 2001:DB8::1470::200 has two double - colons which is incorrect as only one double - colon can be used to represent consecutive 0s in an IPv6 address.
  • Option 3: 2001:0DB8:0:147::02 has incorrect segment representation and incorrect use of double - colon.
  • Option 4: 2001:DB8:0:1470::200 is the correct shortest representation following the IPv6 address shortening rules.

Answer:

2001:DB8:0:1470::200
