Reverse Address Resolution Protocol (RARP)
● Not with all operating systems an IP address is assigned to a computer
during startup. How does such a computer receive its IP address after
booting?
● With the help of Reverse ARP, well-known hardware addresses are
assigned to IP-addresses.
● RARP makes it possible that a booted machine broadcasts its hardware
address and gets back by a RARP server the appropriate IP address.
