Which RFC number is associated with the Boot Protocol (BOOTP)?

The Boot Protocol (BOOTP) is associated with RFC 951. This document provides the specifications for BOOTP, which is a network protocol that allows a client to obtain an IP address and other configuration information from a server during the boot process. BOOTP is designed to enable networked devices, particularly diskless workstations, to communicate over a network and automatically configure themselves with necessary networking parameters.

Being the foundational document governing BOOTP, RFC 951 outlines how BOOTP messages should be structured, the process of interaction between client and server, and the necessary fields within the protocol. It serves as a fundamental building block for later protocols, such as the Dynamic Host Configuration Protocol (DHCP), which evolved from BOOTP to provide more dynamic and flexible IP address allocation.

The other RFC numbers mentioned are not related to BOOTP; instead, they pertain to other networking protocols or specifications that serve different purposes within the networking field. Therefore, RFC 951 is the definitive reference for those studying Boot Protocol specifications.
