It uses ICMP protocol - Internet Control Message Protocol
ARP stands for Address Resolution Protocol, a network layer protocol used to convert an IP address into a physical address, such as an Ethernet address. A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network. The host on the network that has the IP address in the request then replies with its physical hardware address.
The Network Layer in the TCP/IP model is responsible for routing data packets between different networks. It determines the best path for data to travel from the source to the destination through various interconnected networks. The Internet Protocol (IP) is the main protocol used at this layer to address and forward packets.
Network Control Protocol is uses to identify the Network layer protocol used in the packet
RARP (Reverse Address Resolution Protocol) maps layer 2 addresses to layer 3 addresses. ARP (Address Resolution Protocol) maps layer 3 addresses to layer 2 addresses.
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
TCP is the protocol of network layer, It is connection oriented protocol. UDP is the protocol of network layer, It is connection less protocol.
IP is a layer 3 (network layer) protocol used for routing
ICMP
A network layer refers to one of the actual 7 layers. The network layer protocol is actually the system it uses, possibly the order that the layers are done by?
Answer = ARPMeaning of ARP - "Address Resolution Protocol", is used to map IP Network addresses to the hardware (Media Access Control sub layer) addresses used by the data link protocol. The ARP protocol operates between the network layer and the data link layer in the Open System Interconnection (OSI) model.
