It isn't a program; it's a basic part of the TCP/IP protocol.Answer:Well, if you are referring to the DHCP client, the program /sbin/dhclient is likely already installed on your Linux distro of choice.If you would like to run a DHCP server for one or more DHCP client machines or devices, you would go to www.isc.org and download the dhcp.x.x.x package (whatever the latest and greatest version is) and compile it on your Linux host machine. After compilation, configure it as desired, launch dhcpd (usually via the service command or directly from /etc/init.d), the DHCP daemon and you're ready to boot your DHCP clients.
