Why do we need IP address if we have MAC address?
The main difference between MAC and IP address is that, MAC Address is used to ensure the physical address of computer. It uniquely identifies the devices on a network. While IP address are used to uniquely identifies the connection of network with that device take part in a network.
What is the use of IP address and MAC address?
What Is the Use of IP Addresses and MAC Addresses? The IP address is used to transport data from one network to another network using the TCP/IP protocol. The MAC address is used to deliver the data to the right device on a network.
Why do we require IP address?
Why DO WE NEED IP ADDRESSES? IP addresses are the numbers that enable our computers, servers, telephones, cameras, printers and sensors to communicate with each other. Without IP addresses, we would have to copy data from device to device manually, using CDs, DVDs, hard disks or flash storage, such as a USB drive.
Can MAC address be changed?
All MAC addresses are hard-coded into a network card and can never be changed. However, you can change or spoof the MAC address in the operating system itself using a few simple tricks.
Why do we need IP address when the MAC address is unique?
A MAC address (physical addresses) is used for distribution of information with in the network segment. The Ethernet uses MAC address to transfer data between hosts. When its used with IP network, the IP address is resolved using ARP protocol to find the MAC address of the end device and the data is transmitted.
Why do we use MAC address in switch?
Since Switch is a layer 2 device, and it uses MAC addresses to interact with other Hosts within the Network, then why do we use IP addresses within our local networks? Well let’s start with what traffic you’re sending.
When did the IP address and MAC address come out?
IP Addresses and MAC addresses were developed around the same time (circa 1974) but were answers to two, very different problems.
Why do we still need an IP address?
I doubt that anyone really wants to type http://00c0.9b4a.fb2c/just so they can avoid 20 extra bytes in each packet. This is just an example of the work required. What if someone do not need to connect to any host or network outside its own network, Why do he still needs to have an IP address, isn’t MAC address is enough?
