Compressing IPv6 Address for Configuration | Cisco Exam 200-301

Compressed IPv6 Address for Simplified Configuration


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?



Click on the arrows to vote for the correct answer

A. B. C. D.


The original IPv6 address is 2001:0EB8:00C1:2200:0001:0000:0000:0331/64. In IPv6, leading zeros can be omitted, so the address can be simplified as follows:


Next, any consecutive blocks of zeros can be replaced with a double colon (::), but this can only be done once in an address. In this case, there are two blocks of zeros, so we can replace one of them with ::. The result is:


Therefore, the correct answer is D. ipv6 address 2001:EB8:C1:2200:1::331/64.
