When two IP-enabled devices on the same network segment want to communicate, they do so using the low-level protocols and addressing mechanisms defined for the specific medium in use.

For example, Ethernet devices use Ethernet-specific addresses when they communicate with each other, while Frame Relay networks use Frame Relay-specific addresses.

In order for IP systems to communicate with each other, they must first be able to identify the hardware addresses of the other devices on the same network segment that the local device is on. This service is provided by the Address Resolution Protocol.
