The computers of the local network are configured automatically to obtain an IP address. This feature is also reflected in the name. DHCP means: 'Dynamic Host Configuration Protocol'.
# apt-get install dhcp
Message
There is no valid configuration settings. Therefore, the following message appears after installation (translated): Starting DHCP server: dhcpd failed to start - check syslog for diagnostics
Starting the DHCP server: dhcpd startup failed - refer to your syslog to find the error.
In /etc/syslog you see:
No subnet declaration for eth0. Please write a subnet declaration in your dhcpd.conf file for the network segment to Which eth interface is attached.
No Subnetdescription for eth0. Please write a subnet description in your dhcpd.conf file for the network segment to which the interface is connected to eth0.

# Hosts which require special configuration options can

# 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 subnetto 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 shouldbe 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.
