in thread Help with sorting/randomizing?

Thanks Grandfather. Yes, I know it doesn't generate anything yet. I am trying to work on it to provide random ranges.

This is all greek to me. I am thinking maybe counting %hash and iterating over the items.

Your code provides the randomness. However, it still have sequential Class-C ranges that I am trying to avoid:

64.3.71.100 64.3.71.98 66.1.73.23 66.1.73.21

This script is for a firewall. It should not have consecutive Class-C's

Best solution seems to be JavaFan's. If only I could shuffle Class-A's on that one

    There is a vast difference between "random" and "meets some ordering criteria". If you have a constraint on the ordering that you want to meet (if possible, it may not be possible of course) you really need to tell us what that constraint is. Telling us about the bigger picture is often useful too so long as it makes the reason for the constraint clear - I can't imagine why somewhat random ordering is important in the context of a firewall.

    I'm having trouble judging your coding ability so I didn't ease up on the sample code. However you should ask about anything that doesn't make sense to you - we are about helping you learn after all, so if you understood everything your scope for learning is fairly limited!

    Here is one hint: pickEm is recursive and so, effectively, is %ips.

    True laziness is hard work
