  1. Lecture 8 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 diagram Dr. Hussam Dheaa Kamel

  2. 8.1 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. The topics discussed in this section include: Operation Packet Format

  9. 8.2 DHCP The Dynamic Host Configuration Protocol (DHCP) provides static and dynamic address allocation that can be manual or automatic. The topics discussed in this section include: Static Address Allocation Dynamic Address Allocation Manual and Automatic Configuration Packet Format Transition States Exchanging Messages
