What is DHCP and how does it vary to BootP?

A. BootP initialises and automatically assigns the IP address of the instrument on Power up. The BootP server must have knowledge of the MAC address of the instrument. Whereas DHCP can be set to reinitialise or lease the address, subnet mask, DNS name, and other parameters, dynamically or at certain periods (24Hrs for example). DHCP does not necessarily have to have prior knowledge of the instrument. Depending on the setup of DHCP the instrument may not be guaranteed the same IP address every time. DHCP can reduce the overhead of maintaining a network of instruments. The selection of Specified, BootP or DHCP IP addressing is really dependant on local IT requirements.
