When a packet comes from the internet to your router, the router needs both the IP address and the MAC address to successfully deliver the packet to the correct device on your local network. Here's why both addresses are necessary: 1. **Routing at the Network Layer (IP):** Routers operate at the network layer (Layer 3) of the OSI model. They use IP addresses to route packets between different networks. When a packet arrives at your router from the internet, the router examines the destination IP address to determine which device on your local network should receive the packet. 2. **Local Network Delivery at the Data Link Layer (MAC):** Once the router knows which device on your local network should receive the packet based on the IP address, it needs the MAC address to deliver the packet at the data link layer (Layer 2). The MAC address is used for communication within a local network. Each device on a network has a unique MAC address assigned to its network interface card (NIC). The router uses the ARP (Address Resolution Protocol) to map the IP address to the corresponding MAC address within the local network. In summary, while IP addresses are used for routing packets between networks, MAC addresses are used for delivering packets within a local network. The combination of both addresses allows the router to correctly route the packet to the specific device on the local network.

if a packet comes from internet then my router can just send it to my private ip address why Mac address is needed then
When a packet comes from the internet to your router, the router needs both the IP address and the MAC address to successfully deliver the packet to the correct device on your local network.
Here's why both addresses are necessary:
1. **Routing at the Network Layer (IP):** Routers operate at the network layer (Layer 3) of the OSI model. They use IP addresses to route packets between different networks. When a packet arrives at your router from the internet, the router examines the destination IP address to determine which device on your local network should receive the packet.
2. **Local Network Delivery at the Data Link Layer (MAC):** Once the router knows which device on your local network should receive the packet based on the IP address, it needs the MAC address to deliver the packet at the data link layer (Layer 2). The MAC address is used for communication within a local network. Each device on a network has a unique MAC address assigned to its network interface card (NIC). The router uses the ARP (Address Resolution Protocol) to map the IP address to the corresponding MAC address within the local network.
In summary, while IP addresses are used for routing packets between networks, MAC addresses are used for delivering packets within a local network. The combination of both addresses allows the router to correctly route the packet to the specific device on the local network.
