zeromind and mmoll make ddns-update-style adjustable
ISC DHCP supports DDNS update style 'standard' since version 4.3, which implements DDNS as described in RFC 2136, available on Debian since Jessie/8.
This has also been backported to the ISC DHCP server available in RHEL 7.5, see https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.5_release_notes/new_features_networking#BZ1394727

Not adding the 'ad-hoc' DDNS update style as that's been marked as deprecated in ISC DHCP 4.2 and does not work according to the dhcpd.conf man page, it has been removed in 4.3.

DHCP module for Puppet

DHCP module for theforeman. Based on original DHCP module by ZLeslie, thanks to him for the original work.

Installs and manages a DHCP server.

Dependencies

Features

  • Multiple subnet support
  • Host reservations
  • Secure dynamic DNS updates when combined with Bind
  • Failover support

Usage

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

class { 'dhcp':
  dnsdomain    => [
    'dc1.example.net',
    '1.0.10.in-addr.arpa',
    ],
  nameservers  => ['10.0.1.20'],
  interfaces   => ['eth0'],
  dnsupdatekey => "/etc/bind/keys.d/$ddnskeyname",
  require      => Bind::Key[ $ddnskeyname ],
  pxeserver    => '10.0.1.50',
  pxefilename  => 'pxelinux.0',
}

dhcp::pool

Define the pool attributes

dhcp::pool{ 'ops.dc1.example.net':
  network => '10.0.1.0',
  mask    => '255.255.255.0',
  range   => '10.0.1.100 10.0.1.200',
  gateway => '10.0.1.1',
}

Override global attributes with pool specific

dhcp::pool{ 'ops.dc1.example.net':
  network     => '10.0.1.0',
  mask        => '255.255.255.0',
  range       => '10.0.1.100 10.0.1.200',
  gateway     => '10.0.1.1',
  nameservers => ['10.0.1.2', '10.0.2.2'],
  pxeserver   => '10.0.1.2',
}

For the support of static routes (RFC3442):

dhcp::pool{ 'ops.dc1.example.net':
  network => '10.0.1.0',
  mask    => '255.255.255.0',
  range   => '10.0.1.100 10.0.1.200',
  gateway => $gw,
  static_routes =>  [ { 'mask' => '32', 'network' => '169.254.169.254', 'gateway' => $ip },
                      { 'mask' => '0',                                  'gateway' => $gw } ],
}

dhcp::host

Create host reservations.

dhcp::host {
  'server1': mac => "00:50:56:00:00:01", ip => "10.0.1.51";
  'server2': mac => "00:50:56:00:00:02", ip => "10.0.1.52";
  'server3': mac => "00:50:56:00:00:03", ip => "10.0.1.53";
}
