Dynamic Host Configuration Protocol

As its name implies, Dynamic Host Configuration Protocol (DHCP) configures hosts for connection to your network. DHCP enables a network administrator to configure all TCP/IP parameters for each host as he connects to the network after activation of a NIC. These parameters include automatically assigning an IP address to a NIC, setting name server entries in /etc/resolv.conf, and configuring default routing and gateway information for a host. This section first describes how to use DHCP to obtain IP address assignment for your NIC and then how to quickly set up and start a DHCP server using Ubuntu.

Note

You can learn more about DHCP by reading RFC 2131, “Dynamic Host Configuration Protocol,” at www.ietf.org/rfc/rfc2131.txt ...
