DHCP
With so many settings (IP address, subnet mask, default gateway, DNS servers) to specify, the typical TCP/IP network administrator can spend days properly configuring each host manually.

Fortunately, TCP/IP provides a protocol that takes much of the drudgery out of TCP/IP configuration: DHCP.
