Chapter 14 uses DHCP to dynamically manage host addresses.

This chapter explains the Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configuration Protocol), which is used to effectively improve the utilization of IP addresses, improve configuration efficiency, and reduce management and maintenance costs by using parameters such as IP addresses, subnet masks, gateway addresses, and DNS addresses for hosts within the automated authority domain network.

This chapter explains in detail the method of configuring and deploying dhcpd service program in Linux system, analyzes the function of each parameter in dhcpd service program configuration file, and makes readers appreciate the power of DHCP protocol more intuitively through experiments such as automatic allocation of IP address, binding IP address and MAC address.
