DNS packets are just that, packets. They are sent through the same mechanisms as most all other packets on the box, they use the same routing table, etc. I'm hesitant to say they're precisely the same as ping for reasons I won't go into (google ping raw socket), but for your purposes they're the same. Are you sure the server you're trying to make DNS requests to will return responses to your source IP? Most random DNS servers on the internet don't do recursive queries for just anyone (it adds load, and tends to make sploits like cache poisoning attacks easier). Check that first off. Then, if it's still busted, explain your network setup more thoroughly, as that's the next-most-likely culprit. Aaron S.
