nxdomain's Introduction

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.

nxdomain's Issues

Merge into CoreDNS?

I'd like to advocate for this plugin to be included in the main CoreDNS plugins. It's extremely useful to be able to NXDOMAIN calls for zones that you're authoritative for, once they exhaust all other plugins, rather than SERVFAIL anything that wasn't explicitly covered by a plugin.
