Hi Bulldogs!


Time for another new CCNA practice exam - and this one's for you CCNP Bulldogs, too!


Let's get right to it!  I've posted an IPv6 address here, and you need to use your compression superpowers to make it as short as possible.

Legally, of course.  Superpowers should never be used for illegal purposes.


The address to compress:

2200:0000:0000:1111:0333:0000:0440:0550


Answer right after this quick, important message!

The address to compress:

2200:0000:0000:1111:0333:0000:0440:0550

The best way to handle this one is to perform zero compression on blocks 2 and 3, and leading zero compression on blocks 5, 6, 7, and 8. 

You can only perform zero compression once, and to get the shortest address possible, use it on the two consecutive blocks of all zeroes rather than the one standing alone.

Result:  2200::1111:333:0:440:550

And watch those trailing zeroes -- you can't compress those!
