I'm afraid I can't make out what you're asking.
The code doesn't seem very malicious to me -- it searches for TFTP servers on a (somewhat reduced) /16 netblock and tries to upload a file.
There's also a very poorly designed hash called %state that keeps a counter on how many times the host responded to two kinds of ping or TFTP. And that's the hash you are trying to do something to. I'm guessing you want to flatten it to an array, but I don't think that is easy to do until you're familiar with complex data structures.
May I recommend reading perldsc, and then Data::Dumper to visualise the hash? Or building your array inside the nested loop?
Also, you should tell the person who wrote that body of code that it is of poor quality. (Hey, (cr|h)ackers need critique, too.)
