I've got a server which I host my company website as well as some of my clients. I noticed a domain which I created, but never used, was being attacked by a poke and hope hacker. I imagine that the hacker collected the domain from either hitting my DNS server and requesting what domains are hosted.

So, in the interest of prevention and better server management, how would I ask my own DNS server (Linux CentOS 4) what sites are being hosted on it?

Also, is there a way to prevent these types of attacks by hiding this information? I would assume that DNS servers would need to keep some information public, but I'm not sure if there is something that most hosts do to help prevent these bandwidth wasting poke and hope attacks.

Thanks in advance.
