Does router use MAC address or IP address?

Does router use MAC address or IP address?

These create a logical address structure that makes it possible to build networks of networks, ultimately covering the earth. So your router has a MAC address so the various machines can talk to each other using Ethernet, and a IP address to communicate with the world.

Why do we need IP address and MAC address both?

So again, IP Addresses are logical and routeable addresses. And that’s why computers have both MAC Addresses and IP Addresses. MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.

Which is more important IP address or MAC address?

MAC addresses are only used for communication on Local Area Networks (LANs), so if you want to access a remote network or the Internet, you need an IP address.

What does the routing table contains?

The routing table contains network/next hop associations. These associations tell a router that a particular destination can be optimally reached by sending the packet to a specific router that represents the next hop on the way to the final destination.

Why do routers need MAC addresses?

A DHCP server (like your router) uses a MAC address to assign an IP address to a network adapter. Without MAC, an adapter can’t get an IP address. Without an IP address, the device can’t connect at all. When this happens within the network, the device will get the same IP address each time it connects.

What is the relationship between an IP address and a MAC address?

MAC address is assigned by the manufacturer of the hardware interface while the IP address is assigned by the network administrator or Internet Service Provider (ISP). Mac address defines the devices identity, but IP address describes how the devices are connected to the network.

Do routing tables contain MAC addresses?

The routing table doesnot contain MAC address. It is only the learnt routes and the next hop ( which is the exit interface or the next hop router ) that gets stored in routing table.

Does a router use a MAC address table?

Does a router maintain a MAC table like a switch? The reason most or pretty much all routers do store MAC addresses is because they offer multiple network ports which operate on switching level (Layer 2, Data Link).
