Blocking hosts.

Hi,

I have a small home network of Windows machines with an Ubuntu machine
acting as an ICS gateway, and firewall. I want to block the windows
machines from accessing certain hosts. Trouble is, iptables blocks
IPs, not hostnames.

I think the best way to proceed would be to configure the firewall to
block the DNS protocol, and add a DNS server, and then enable only
traffic to that, while also black holing the offending hostname.

Does that sound like the best way to do this?
