Network Layer
PACKET INTERNET GROPER uses ICMP echo request and reply messages to check the physical and logical connectivity of machines on an internetwork . Hence Ping works on layer 3 of OSI model.

internetwork
core layer
Internetwork travel occurs at the Network Layer (Layer 3) of the OSI model. This layer is responsible for routing data packets between different networks, ensuring they reach their destination across diverse network segments. It handles logical addressing, typically using IP addresses, and facilitates the establishment of paths for data transmission through routers.
The layer responsible for determining the best path a packet should travel across an internetwork is the Network layer, which is Layer 3 of the OSI model. This layer uses routing protocols and algorithms to analyze network conditions and select the most efficient route for data packets. Devices such as routers operate at this layer to facilitate the forwarding of packets between different networks.

Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
