Answers for Part II
So the answers to the exciting tasks at hand....
There was a good amount of activity surrounding answers submitted for the contest! It was good to see that many people interested in them! Now, it's time to go through the answers and stretch the imagination a bit! Be prepared for some stretching as well!
One quick thing to point out before we get started, there was a question asked about why /24 routes won't have a ".255" as the fourth octet. This really depends on how we are using the ACL. If we are doing traffic filtering, where packets will obviously come from hosts INSIDE the /24, then yes, I'd use a ".255" mask.
However, when the entry is being used for a routing filter, and it's a /24 route... The fourth octet will, by definition, always be ".0" and shouldn't be changed. So the mask of ".0" prevents anything from changing!
Now... On to the answers!
