My server acts as a secondary nameserver for primate.net, in which zone
it is named ns.de.primate.net. I set that up long ago for a friend, and
forgot all about it. Until now.
Imagine my surprise when I discovered the other day that Google crawled
various pages on my site as "http://ns.de.primate.net/whatever", and was
happily presenting (some of) those results in preference to their proper
It's true that the site is reachable as ns.de.primate.net, and Apache
will—since it doesn't recognise that name—serve the default VirtualHost,
which is toroid.org. But I can't imagine why Google ever decided to use
that name. I've never used it in a URL, public or otherwise. As far as I
know, it's never been used for anything but name service for primate.net
(and certainly not in a PTR record for my server's address).
I hope Google doesn't take it upon itself to use any of the other names
by which my server happens to be accessible. Just in case, I added the
following as the first (i.e. default) virtualhost in my httpd.conf. Now
any request to a not-explicitly-configured name will be redirected to
Redirect permanent / http://toroid.org/
We can't have
running around, after all.
