# dhcpd.conf

# Configuration file for ISC dhcpd

# Hosts with more than one interface MUST specify a ``server-identifier'',
# which should be the IP address of the server's primary network interface,
# or if there is no interface that can be described that way, at least an
# interface whose address isn't likely to change.

server-identifier toccata.fugue.com;

# option definitions common to all supported networks...
option domain-name "fugue.com";
option domain-name-servers toccata.fugue.com;

# Shared network declaration is used to group subnets which share the same
# physical network together.   The name is specified so that the shared
# network can be referred to in log messages - it serves no other function.

# One of the two IP subnets that share this physical network
#
# Address ranges can be specified for each subnet attached to
# a shared network.   Since these subnets share the same physical
# network, addresses are pooled together, and assignments are made
# without regard to the actual subnet.   If the optional dynamic-bootp
# keyword is given in the address range declaration, then addresses
# in that range can be assigned either with the DHCP protocol or the
# BOOTP protocol; otherwise, only DHCP clients will have addresses
# allocated from the address range.
#
# Note that each IP subnet can have its own options specific to that subnet.
# options that aren't specified in the subnet are taken from the shared
# network (if any) and then from the global option list.

# supersede the global options specified earlier.

# 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.

# If a DHCP or BOOTP client is mobile and might be connected to a variety
# of networks, more than one fixed address for that host can be specified.
# Hosts can have fixed addresses on some networks, but receive dynamically
# allocated address on other subnets; in order to support this, a host
# declaration for that client must be given which does not have a fixed
# address.   If a client should get different parameters depending on
# what subnet it boots on, host declarations for each such network should
# be given.   Finally, if a domain name is given for a host's fixed address
# and that domain name evaluates to more than one address, the address
# corresponding to the network to which the client is attached, if any,
# will be assigned.
