  # The ddns-updates-style parameter controls whether or not the server will
  # attempt to do a DNS update when a lease is confirmed. We default to the
  # behavior of the version 2 packages ('none', since DHCP v2 didn't
  # have support for DDNS.)

  # Hosts which require special configuration options can be listed in
  # host statements.   If no address is specified, the address will be
  # allocated dynamically (if possible), but the host-specific information
  # will still come from the host declaration.

  # Fixed IP addresses can also be specified for hosts.   These addresses
  # should not also be listed as being available for dynamic assignment.
  # Hosts for which fixed IP addresses have been specified can boot using
  # BOOTP or DHCP.   Hosts for which no fixed address is specified can only
  # be booted with DHCP, unless there is an address range on the subnet
  # to which a BOOTP client is connected which has the dynamic-bootp flag
  # set.

  # You can declare a class of clients and then do address allocation
  # based on that.   The example below shows a case where all clients
  # in a certain class get addresses on the 10.17.224/24 subnet, and all
  # other clients get addresses on the 10.0.29/24 subnet.
  
  #class "foo" {
