Which two reductions are the correct reductions if the IPv6 address 2001:0d02:0000:0000:0014:0000:0000:0095? (Choose two)

A. 2001:0d02:::0014:::0095

B. 2001:d02::14::95

C. 2001:d02:0:0:14::95

D. 2001:d02::14:0:0:95








 

Suggested Answer: CD

We can't use triple colons (:::) in IPv6 presentation. Also we can't use double colons (::) twice. You can use it only once in any address because if two double colons are placed in the same address, there will be no way to identify the size of each block of 0s.
Remember the following techniques to shorten an IPv6 address:
- Omit leading 0s in the address field, so :0000 can be compressed to just and :0d02 can be compressed to :d02 (but :1d00 can not be compressed to :1d)
- Use double colons (::), but just once, to represent a contiguous block of 0s,
So -
2001:0d02:0000:0000:0014:0000:0000:0095 can be compressed to
2001:d02:0:0:14::95
OR -
2001:d02::14:0:0:95
