I just hate to be a smartarse, but that isn't so.
arp is needed by an Ethernet network, as it is a shared access bus
structure (I don't have the correct acronym to hand).
Basically, all ethernets are in their little hear of hearts long runs of
thick yellow coax cable. A station identifies itself uniquely by its MAC
(media access control) address. The arp protocol enables a mapping
between MAC addresses and IP addresses.
