BOOTP, which brings additional option configuration to the historical RARP protocol (see RFC903) which provides only IP address, has itself evolved in the DHCP protocol. X11 diskless display screen no longer exists, but many devices can take advantage of being configured at their network access time – for example IoT devices. When starting such a device, BOOTP provides sufficient configuration parameters for obtaining network access, firmware and software locations for images to be downloaded from a network file repository. In addition to providing the IP address, the DHCP protocol is able to set a large bunch of options that are very useful for device configuration.ĭHCP is an evolution of the BOOTP protocol (see RFC951) designed at first to bootstrap a diskless client. Supplying DHCP options is a smart way to configure network clients during the early phase of network access deployment.
