  1. 1. Chapter 16 Host Configuration: BOOTP and DHCP Objectives Upon completion you will be able to: • Know the types of information required by a system on boot-up • Know how BOOTP operates • Know how DHCP operates • Understand the differences between BOOTP and DHCP • Understand the DHCP transition state diagramTCP/IP Protocol Suite 1
  2. 2. 16.1 BOOTP The Bootstrap Protocol (BOOTP) is a client/server protocol that configures a diskless computer or a computer that is booted for the first time. BOOTP provides the IP address, net mask, the address of a default router, and the address of a name server.
