Part of Golf is how to hit the ball to reach the target. [Smile]

I can tell you my approach, so far everything is being done with the binary representations of IP addresses. I just have the IP address array left to be coded but already have a rough idea how to solve that one.

Then it's down to consolidating code fragments to make them shorter and reduce the number and length or variables.

I also do not see anything complicated in there, a couple of binary ANDs and knowing what patterns to look for in a binary IP format.

Just be aware that the second round is shortened and only goes from Friday afternoon to Wednesday afternoon.
