AFAIK such double reverse resolves are, while uncommon, perfectly legal.

Best guess is a script kiddie looking for vulnerable host. Whether it's 
for an old or a new attack is anybody's guess. Just be sure your 
installation is current.

Well, you shouldn't be worried about your privacy - you *do* off er a 
web server, so anybody can query it. If you don't want that, don't run 
a webserver, or don't have it open to the public.

Also, you seem to have a phpinfo.php in your home - do you really want 
to publish that information? I'm sorry to tell you, but if you don't 
want to publish that information, why do you offer that file?

As for statistics: put in a robots.txt file (User-Agent: *\nDisallow: /) 
in your web home. Legitimate companies will respect that. Other than 
that, you can't really do much about it, except making access 
inconvenient for automated web-spidering - but this will also make it 
invonventient for human users...
