Installs and manages a DHCP server.


  • Multiple subnet support
  • Host reservations
  • Secure dynamic DNS updates when combined with Bind
  • Can create a dummy (ignored) subnet so that the server can be used only as a helper-address target


Define the server and the zones it will be responsible for.

class { 'dhcp':
  service_ensure => running,
  dnsdomain      => [
  nameservers  => [''],
  ntpservers   => ['us.pool.ntp.org'],
  interfaces   => ['eth0'],
  dnsupdatekey => '/etc/bind/keys.d/rndc.key',
  dnskeyname   => 'rndc-key',
  require      => Bind::Key['rndc-key'],
  pxeserver    => '',
  pxefilename  => 'pxelinux.0',
  omapi_port   => 7911,


Define the pool attributes. This example will create a pool, which serves IPs of two different ranges in the same network.

May be passed as a hash into the DHCP class.

dhcp::pool{ 'ops.dc1.example.net':
  network => '',
  mask    => '',
  range   => ['', '' ],
  gateway => '',


Define a subnet that will be ignored - useful for making the DHCP server only respond to requests forwarded by switches etc.

May be passed as a hash into the DHCP class.

dhcp::ignoredsubnet{ 'eth0':
  network => '',
  mask    => '',


Create host reservations.

May be passed as a hash into the DHCP class.

dhcp::host { 'server1':
  comment            => 'Optional descriptive comment',
  mac                => '00:50:56:00:00:01',
  ip                 => '',
  # Optionally override subnet/global settings for some hosts.
  default_lease_time => 600,
  max_lease_time     => 900,
  # Optionally declare event statements in any combination.
  on_commit => [
    'set ClientIP = binary-to-ascii(10, 8, ".", leased-address)',
    'execute("/usr/local/bin/my_dhcp_helper.sh", ClientIP)'
  on_release => [
    'set ClientIP = binary-to-ascii(10, 8, ".", leased-address)',
    'log(concat("Released IP: ", ClientIP))'
  on_expiry => [
    'set ClientIP = binary-to-ascii(10, 8, ".", leased-address)',
    'log(concat("Expired IP: ", ClientIP))'


Parameters are available to configure pxe or ipxe

Boot ipxe from pxe. When configured this overrides pxefilename. For more information see ipxe.org.

class { 'dhcp':
  ipxe_filename  => 'undionly.kpxe',
  ipxe_bootstrap => 'bootstrap.kpxe',
  pxeserver      => '',
