Hey, Yes, you can simply use BIND to do this. Just put the entry in backwards and have it resolve to 127.0.0.2 or something, for example, to look up the ip address for 1.2.3.4, you would need to do:
4.3.2.1.bl.domain.com. resolve to 127.0.0.2. Personally, I wrote my own system that keeps blacklisted IP's in a mySQL database, where I can easily add and remove them, then they are regularly pulled to my master zone file, and serial automatically incremented. That's how I handle http://bl.blueshore.net/ I'm not sure if there's any software available, but if it would be helpful, I might put together my stuff into some sort of downloadable application for people to use, depends on how much of a demand there would be for it. Hope this helps, Richard _____________________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vincent Jordan Sent: Tuesday, November 11, 2003 2:12 PM To: [EMAIL PROTECTED] Subject: [IMail Forum] DNS Blacklists I've thought about maintaining a dns blacklist in house to help control some of the spam issues. Can this be done with any dns server ( bind ) or are there some apps already made to take care of this.
