resolving whole domains to a single IP with bind


I'm looking to map every possible hostname in a domain to a single IP address eg:

i have a domain name sdf.com and i want any host within this domain to resolve to so,
nslookup fsdf.sdf.com returns

as would sdfasdf.sdf.com or d3.sd.sdf.com

does anyone know how to accomplish this with bind?

I think having only:

*    IN A

in your zone file will do it. Out of curiosity why would you want to do this?

I want to redirect people going to sites like kazaa.com and *.gator.com etc to a page I will create.

Okay... That will work as long as they only use your DNS server. A knowlegeable user can simply set their machine to use a DNS server on the Internet and bypass your restriction. Or, even if you block DNS at a firewall so they have to use your DNS server they can create a hosts file record for the site.

That presumes that the ultimate goal is to block folks from using kazaa, gator, or other P2P clients. A better approach, if you want to work off the IP's is to block access to those IP's at a firewall or router. That solution only works for IP's that you know about or TCP/UDP ports that you know. A more complete solution, that works on the content of packets, is somthing like Packeteer or P2P WatchDog (http://www.p2pwatchdog.com/home.html).
