The DHCP service daemon. Command-line arguments enable you to set several runtime options.



Used to configure and unconfigure a DHCP server. This utility enables you to perform many of the functions of DHCP Manager from the command line. This utility is primarily intended for use in scripts for sites that want to automate some configuration functions. dhcpconfig collects information from the server system's network topology files to create useful information for the initial configuration.



Used to add, delete, and modify configuration options and macros for DHCP clients. This utility lets you edit the dhcptab table indirectly, which ensures the correct format of the dhcptab table. You should not directly edit the dhcptab table.



Used to manage the DHCP network tables. You can use this utility to perform the following tasks:

  • Add and remove IP addresses and networks under DHCP management.

  • Modify the network configuration for specified IP addresses.

  • Display information about IP addresses and networks under DHCP management.
