One additional question -->

Just think "IP and Port No" are enough to identify a process on a host  then what is the requirement of ARP ?
and RARP does option C?
at router we dont know port number rt ... so ip+port could not identify

RARP Is option c
which protocol can be used for getting default gateway's IP???
