Acutally I was referring to the browser "feature" of trying if
"" wasn't answering as not being RFC defined behavior. I aggree
that sysadmins can setup their domains and webservers anyway that want.

The point I wanted to make, but didn't relate properly is that 90+% of the
time, when someone is making a HTTP request to when they should
have asked for, the best thing to do is to just send them to Since these people are part of that 97% anyways, and any
thing you tell them about using the correct URL is going to go over their
heads, it would be best if they just got to the webserver without knowing
that anything happened. The easiest way to do that is just to resolve them
to the same IP address in the domain record.

But it doesn't have to be setup this way. You can send them to a whole
different computer if you want to. But why would you want to do that? You
are just going to get email from "" saything that your
website don't work.
