	The problem is, DNS is just that way. If you don't get it exactly right,
it won't work.

	Try actually loading up a zone file that looks like that and you'll see
what I mean.

	So why are we having this conversation? You obviously don't understand
what I'm talking about, and you don't have enough background to be
disagreeing with me. I'm not trying to be rude, but I hate seeing people
