In your named.conf, you will find this:

// If you've got a DNS server around at your upstream provider, enter
// its IP address here, and enable the line below.  This will make you
// benefit from its cache, thus reduce overall DNS traffic in the Internet.
/*
        forwarders {
                127.0.0.1;
        };
*/

I have always turned that on. I like to use my upstream hosts.

Today, I turned it of, because of this:

$ host lkjsdf
lkjsdf has address 199.101.28.20
Host lkjsdf not found: 3(NXDOMAIN)

What’s that IP address? That’s not relevant, but it is important. It’s the hostname of a web assistant engine. My upstream has decided to implement what I think is a dirty hack.

I have since disabled forwarding on all my DNS servers.
