A network administrator is setting up a new IPv6 network using the (CCNA 200-301)
A network administrator is setting up a new IPv6 network using the 64-bit address 2001:0EB8:00C1:2200:0001:0000:0000:0331/64. To simplify the configuration, the administrator has decided to compress the address.
Which IP address must the administrator configure?
A. ipv6 address 2001:EB8:C1:22:1::331/64
B. ipv6 address 21:EB8:C1:2200:1::331/64
C. ipv6 address 2001:EB8:C1:2200:1:0000:331/64
D. ipv6 address 2001:EB8:C1:2200:1::331/64
Solution
Correct answer: D. ipv6 address 2001:EB8:C1:2200:1::331/64.
To simplify the configuration, the network administrator should compress the given IPv6 address 2001:0EB8:00C1:2200:0001:0000:0000:0331/64.
The rules for compressing IPv6 addresses are:
Remove leading zeros from each 16-bit group.
Replace consecutive 16-bit groups of zeros with a double colon (::).
Applying these rules to the given address:
2001:0EB8:00C1:2200:0001:0000:0000:0331
Becomes: 2001:EB8:C1:2200:1::331
Therefore, the compressed IPv6 address that the administrator should configure is 2001:EB8:C1:2200:1::331/64.
The other options are incorrect:
A. This address is missing the leading 2 in the first group.
B. This address is not a valid compression of the given address.
C. This address still has the leading zeros in the last group.
