As one spokesman for the "DNS is tricky and dangerous" crowd, I don't frown upon running it inside your LAN as long as there's no possibility of your internal DNS leaking into the outside world (read: as long as there's no way for outside hosts to query your Xserve).


Allow me to post to someone else's concurrent DNS thread:

This has been one of my biggest questions about DNS: Everyone warns you not to pollute outside DNS with internal "bogus" DNS info, but what are the ways to prevent that?

You mention the obvious: block port 53. What are other things you should do to make sure that your bogus DNS LAN info, or valid DNS LAN hosts you have, but only want to be available internally, don't propagate to the outside world?

Views is another, I guess. What else?

I ask because I don't want to screw things up.
