I disabled DNS recursion in BIND:

CODE

options {
recursion no;
}

to prevent DDoS attacks. After that I added the The Planet monitoring IP adresses:

CODE

options {
    recursion no;
    listen-on {
        12.96.160.0/24
        67.19.0.0/24
        216.234.234.0/24
        70.85.125.0/24
        70.84.160.0/24
    }

But still the status is CRITICAL while the DNS is working fine.
Does anyone know how to have recursion disabled and allow monitoring the DNS?

Not me, sorry.

I'm sure you will get an answer by putting in a ticket.

I've gotten this to work for our internal name servers. Near the bottom of the Service Monitors section in the Monitoring Request form is 'DNS Custom Check'. The value of the domain field should be a DNS record which you know you will always be authoritative for.

Thanks a lot. I submitted the changes using the Monitoring Request form.
