Indeed. But Python boasts that the batteries are included, and given the wealth of other networking facilities that are available, it is a bit of a hole that you can't run DNS queries in this way. Mind you, if Python's managed to get this far without it being a major stumbling-block, that probably means that it's not a serious lack. And I don't think many people write DNS *servers* in Python. (Most people don't write DNS servers at all, since BIND exists. But I did exactly that this week, since it would be easier than most other options.)
