Example of a basic server listening on and issuing leases for the subnet 192.0.2.0/24.

dhcp_install 'isc-dhcp-server'

dhcp_service 'dhcpd' do
  ip_version :ipv4
  action [:create, :enable, :start]
end

dhcp_config '/etc/dhcp/dhcpd.conf' do
  allow %w(booting bootp unknown-clients)
  parameters(
    'default-lease-time' => 7200,
    'max-lease-time' => 86400,
    'update-static-leases' => true,
    'one-lease-per-client' => true,
    'authoritative' => '',
    'ping-check' => true
  )
  options(
    'domain-name' => '"test.domain.local"',
    'domain-name-servers' => '8.8.8.8, 8.8.4.4'
  )
  action :create
end

dhcp_subnet '192.0.2.0' do
  comment 'Basic Subnet Declaration'
  subnet '192.0.2.0'
  netmask '255.255.255.0'
  options [
    'routers 192.168.1.1',
  ]
  pool(
    'peer' => '192.168.0.2',
    'range' => '192.168.1.100 192.168.1.200'
  )
  parameters(
    'ddns-domainname' => '"test.domain"'
  )
end
