nxdomain

Name

nxdomain - shortcut domain resolution by returning NXDOMAIN directly.

Description

nxdomain takes a list of domains and immediately returns NXDOMAIN for any name under them instead of taking the long road of trying to resolve them.

Syntax

nxdomain [ZONE]...

Examples

NXDOMAIN everything in the .com zone:

com {
    nxdomain
    whoami
}

NXDOMAIN everything (might be a bad idea):

. {
    nxdomain
    whoami
}

Bugs

The list of zones is just a slice that is traversed, meaning this plugin will get slow when a lof of names are to be shortcut.
