# No service will be given on this subnet, but declaring it helps the

# DHCP server to understand the network topology.

#subnet 10.152.187.0 netmask 255.255.255.0 {

#}

# This is a very basic subnet declaration.

#subnet 10.254.239.0 netmask 255.255.255.224 {

#  range 10.254.239.10 10.254.239.20;

#  option routers rtr-239-0-1.example.org, rtr-239-0-2.example.org;

#}

# This declaration allows BOOTP clients to get dynamic addresses,

# which we don't really recommend.

#subnet 10.254.239.32 netmask 255.255.255.224 {

#  range dynamic-bootp 10.254.239.40 10.254.239.60;

#  option broadcast-address 10.254.239.31;

#  option routers rtr-239-32-1.example.org;

#}

# A slightly different configuration for an internal subnet.

#subnet 10.5.5.0 netmask 255.255.255.224 {

#  range 10.5.5.26 10.5.5.30;

#  option domain-name-servers ns1.internal.example.org;

#  option domain-name "internal.example.org";

#  option routers 10.5.5.1;

#  option broadcast-address 10.5.5.31;

#  default-lease-time 600;

#  max-lease-time 7200;

#}

# 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.

#host passacaglia {

#  hardware ethernet 0:0:c0:5d:bd:95;

#  filename "vmunix.passacaglia";

#  server-name "toccata.fugue.com";

#}

# 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.

#host fantasia {

#  hardware ethernet 08:00:07:26:c0:a5;

#  fixed-address fantasia.fugue.com;

#}

# 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" {

#  match if substring (option vendor-class-identifier, 0, 4) = "SUNW";

#}

#shared-network 224-29 {

#  subnet 10.17.224.0 netmask 255.255.255.0 {

#    option routers rtr-224.example.org;

#  }

#  subnet 10.0.29.0 netmask 255.255.255.0 {

#    option routers rtr-29.example.org;

#  }

#  pool {

#    allow members of "foo";

#    range 10.17.224.10 10.17.224.250;

#  }

#  pool {

#    deny members of "foo";

#    range 10.0.29.10 10.0.29.230;

#  }

# If you are here to restrict what interfaces should dhcpd listen on,

# be aware that dhcpd listens *only* on interfaces for which it finds subnet

# declaration in dhcpd.conf. It means that explicitly enumerating interfaces

# also on command line should not be required in most cases.

# If you still insist on adding some command line options,

# copy dhcpd.service from /lib/systemd/system to /etc/systemd/system and modify

# it there.
