Greetings. This looks nearly identical to another post, just a few posts down. Yours also?

What "packets" are you looking to send/receive? Given the terse example you provide. It looks like you're only looking for the IN A. The DNS is a protocol, and has rules that must be followed, to properly form correct queries. I strongly recommend learning more about it. As that knowledge will be required to create, and send, as well as knowing what format to expect on return "packets". DNSwatch appears to be a fairly good resource for much of this.

You'll need to setup "queries" in your script/application --
IN (A|AAA|MBOX|NS|SOA|RP|LOC|CNAME|PTR|TXT|SPF|IXFR|AXFR) (to name but a few), if you're looking to make more than one type. If you're on a UNIX-ish system. Try dig, and experiment to learn how to correctly form the queries "packets". While this may seem obvious, I'll ask anyway. Have you looked at the examples provided in Net::DNS? I found the examples were easily used, and modified to suite my own needs.

If you could provide a slightly more specific example of what you wanted, or even a slightly more specific question. It'd be easier to form a specific solution.

Best wishes.
