What you're looking at is a hash of hashes. Each source IP address is given its own hash of corresponding destinations. $srciphash{$ip} is a reference to that hash.

I'd highly recommend looking at the Data Structures Cookbook and perlref POD pages -- these concepts are explained there better than I could hope to do.
