Thanks for the reply mischief,

I actually didn't make that assumption. I could have easily not worried about things being unique until I got to the IP values - but by doing that I am wasting processing power and bandwidth by doing a DNS lookup on the same URL multiple times.

This is why I decided to make sure I pass a unique set of hostnames to the Net:DNS::Resolver and then run the results (IPs (including duplicates)) through the Array::Unique module again.

In fact if you try the script as is and compare the regex results before and after passing through the Array:Unique module you will see I am saving a large amount of duplication.
