I really don't know much details about networking, but there is 23 packages on CPAN when I search for dhcp dhcp, there is probably one for your use there.

Now, waiting is one of those thing you actually can do a lot of at any instance, so threads or multiple proccesses (fork) makes a lot of sense in this case. To know what your results tell you, you will have to exercise fine controll over the number of concurrent requests to the server, i.e. how often to send another request, Time::HiRes can help with that.

Try to start programming, and post code and direct questions if/when you're stuck.

Update: After reading BrowserUk's answer right above; forget what I wrote here and study sundialsvc4's ansver in that other thread. It's very good. cheers
