How can I obtain a user's DNS info?

I've figured out how to obtian someone's IP address using PERL, and I use it to ban unwelcome users from my Message Board. An IP ban is rather hard to implement since most people use dial up ISP's and it's hard to know what range of IP's to ban (especially with AOL). I want to know if it's possible to convert that IP address into DNS info (ex. du-148-233-111-232.prodigy.net.mx). I'm not sure what the exact term for that is. Anyway, if someone knows how I could translate the IP's I'd really like to know! Thanks a lot.
