Method 1: Reverse ARP (RARP)
What is the IP addr of a hardware address?
Need RARP server to respond.
Once IP address is gotten, it does a “tftp” to get its boot image.
Design of the RARP server complex unlike ARP which is integrated into TCP/IP host implementations
- Needs to maintain table for multiple hosts (/etc/ethers)
- Kernel does not process/parse files => RARP is a user process. But does not run over IP.
