4.7 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below
is for guidance only and neither of
these methods should be considered
an endorsement by Puppet.

A puppet module for the Unbound caching resolver.

Supported Platforms

  • Debian
  • FreeBSD
  • OpenBSD
  • OS X (macports)
  • RHEL clones (with EPEL)
  • openSUSE (local repo or obs://server:dns)
  • Archlinux

For an up2date list of supported operating systems and their versions, please check the metadata.json.


To use this module requires at least unbound 1.6.6. Please also consult metadata.json to understand the minimum puppet version and any other module dependencies.


Server Setup

At minimum you should setup the interfaces to listen on and allow access to a few subnets. This will tell unbound which interfaces to listen on, and which networks to allow queries from.

class { "unbound":
  interface => ["::0",""],
  access    => ["","::1"],

Or, using hiera

  - '::0'
  - ''
  - ''
  - '::1'

Stub Zones

These are zones for which you have an authoritative name server and want to direct queries.

unbound::stub { "":
  address  => '',
  insecure => true,

unbound::stub { "":
  address  => '',
  insecure => true,

# port can be specified
unbound::stub { "":
  address  => '',
  insecure => true,

# address can be an array along with nameservers.
# in the following case, generated conf would be as follows:
#   stub-addr:
#   stub-addr:
#   stub-host:
#   stub-host:
# note that conf will be generated in the same order provided.
unbound::stub { "":
  address    => [', ''],
  namservers => [ '', '' ],

Or, using hiera

      - '
      - ''
      - ''
      - ''

Unless you have DNSSEC for your private zones, they are considered insecure, noted by insecure => true.

Static DNS records

For overriding DNS record in zone.

unbound::record { 'test.example.tld':
    type    => 'A',
    content => '',
    ttl     => '14400',

Or, using hiera

    type: 'A'
    content: ''
    ttl: '14400'

Forward Zones

Setup a forward zone with a list of address from which you should resolve queries. You can configure a forward zone with something like the following:

unbound::forward { '.':
  address => [

Or, using hiera

      - ''
      - ''

This means that your server will use the Google DNS servers for any zones that it doesn't know how to reach and cache the result.

Domain Insecure

Sets domain name to be insecure, DNSSEC chain of trust is ignored towards the domain name. So a trust anchor above the domain name can not make the domain secure with a DS record, such a DS record is then ignored. Also keys from DLV are ignored for the domain. Can be given multiple times to specify multiple domains that are treated as if unsigned. If you set trust anchors for the domain they override this setting (and the domain is secured).

class {'unbound:'
  domain_insecure => ['',']

Or, using hiera


Local Zones

Configure a local zone. The type determines the answer to give if there is no match from local-data. The types are deny, refuse, static, transparent, redirect, nodefault, typetranspar- ent, inform, inform_deny, always_transparent, always_refuse, always_nxdomain. See local-zone in the unbound documentation for more information. You can configure a local-zone with something like the following.

class {'unbound:'
  local_zone => { '' => 'nodefault'}

Or, using unbound::localzone

unbound::localzone { '':
  type => 'nodefault'

Or, using hiera

unbound::local_zone: nodefault nodefault

Fine grain access-control

class { "unbound":
  interface => ["::0",""],
  access    => ["", " reject", "::1 allow_snoop"],

The access option allows to pass the action for each subnets, if the action is not provided we assume it’s 'allow'.

Adding arbitrary unbound configuration parameters

class { "unbound":
  interface          => ["::0",""],
  access             => ["","::1"],
  custom_server_conf => [ 'include: "/etc/unbound/conf.d/*.conf"' ],

The custom_server_conf option allows the addition of arbitrary configuration parameters to your server configuration. It expects an array, and each element gets added to the configuration file on a separate line. In the example above, we instruct Unbound to load other configuration files from a subdirectory.

Remote Control

The Unbound remote controls the use of the unbound-control utility to issue commands to the Unbound daemon process.

class { "unbound::remote":
  enable => true,

On some platforms this is needed to function correctly for things like service reloads.

Skipping hints download

In the case you're only building a caching forwarder and don't do iterative lookups you might not want to download the hints file containing the root nameservers because you don't need it, or you also might not be able to download it anyway because your server is firewalled which would cause the module would hang on trying to download the hints file. To skip the download set the skip_roothints_download parameter to true.

class { "unbound":
  skip_roothints_download => true,
