    I need to disable open resolving and recursive calls . what exactly should i put in named.conf ? openresolver.com says my main ip is not vulnerable to DNS Amplification attacks. but my host is null routing some of my additional IPs saying they're a source of such attack.

    Hello :)

    In your /etc/named.conf file, look for:

    Code:
    view    "external" {
    You should see "recursion no;" under this view.

    Thank you.
