| Explanation & Hint:
To compress the IPv6 address fe80:9ea0:0000:2020:0000:00bf:00e0:9290, the following rules should be applied:
- Leading zeros within each 16-bit block of the address can be omitted.
- Consecutive blocks of zeros can be replaced with a double colon (::), but this can only be done once in the address.
Applying these rules, the compressed format of the IPv6 address is:
fe80:9ea0:0:2020:0:bf:e0:9290
Explanation of the options:
- fe80:9ea0::2020:0:bf:e0:9290: Correct. It omits leading zeros and replaces a single block of zeros with a double colon.
- fe80:9:20::b000:290: Incorrect. This changes the structure and values of the original address, not accurately representing it.
- fe80:9ea:0:2200::fe0:290: Incorrect. This does not match the structure or values of the original address.
- fe80::0220:0b3f:f0e0:0029: Incorrect. This also changes the original address’s structure and values, not accurately reflecting it.
The first option, fe80:9ea0::2020:0:bf:e0:9290, correctly represents the compressed format of the given IPv6 address. |
