Imagine my surprise when I discovered the other day that Google crawled various pages on my site as "", and was happily presenting (some of) those results in preference to their proper versions.

It's true that the site is reachable as, and Apache will—since it doesn't recognise that name—serve the default VirtualHost, which is 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 (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

<VirtualHost *:80>

We can't have evil primates running around, after all.
