Reverse ARP (RARP)

• H/w address -> IP address

• Used by diskless systems

  • RARP server responds.
  • Once IP address is obtained, use “tftp” to get a boot image. Extra transaction!

• RARP design complex:

  • RARP request broadcast, not unicast!
  • RARP server is a user process and maintains table for multiple hosts (/etc/ethers). Contrast: no ARP server
