yes , IP address are used by routers . switches can work with MAC address too . Also if case of same network we do not need routers. switches are enough.

You still need an IP address to communicate on the same network (assuming IP communication). The question needs more information.

Chad,
IP addresses are layer three communications which are routers. You dont need a router in the same network, switches use hardware address anyways which is you MAC address.

Every system in network is identified by unique IP address. Therefore I think IP address is essential for communication. Mac address is the machine address. But in network this address is unknown to another machine. What another machine knows is the IP address of the machine and using arp mac address of the machine can be obtained for communication.
Use Only mac address to communicate.
