Does IoT devices have MAC address?
You tried looking at the labels of the physical IoT device and inspecting the paperwork (documentation and/or instruction manual) that came with the device. You still do not know its MAC address. Like all IoT devices, it can connect to a TCP/IP network (e.g., the internet).
Does every device need a MAC address?
No two devices on a local network should ever have the same MAC address. If that does happen, both devices will have communications problems because the local network will get confused about which device should receive the packet.
Why do devices need the MAC address of other devices on the network?
MAC addresses are required to make a local Ethernet (or wifi) network function. They allow a network device to attract the attention of a single directly connected device, even though the physical connection is shared. This can be important when thousands of devices are connected together within a single organisation.
What is MAC Address and why it is required?
The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Computer operating systems and broadband routers support viewing and sometimes changing MAC addresses.
What is the main problem with MAC Address based communication over the internet instead of IP address?
What is the main problem with MAC address based communication over the Internet instead of IP address? – Quora. Scale. There are MAC addresses available. The only organizational structure of them is by manufacturer grouping, which is completely useless for routing purposes.
Can we communicate with MAC address?
1 Answer. You are correct. ARP does communicate on the same subnet using MAC addresses. Your answer could be improved to include that the computers have to be on the same subnet.
Why MAC address is important for creating a network?
The MAC address is an important element of computer networking. MAC addresses uniquely identify a computer on the LAN. MAC is an essential component required for network protocols like TCP/IP to function. Changing a MAC address can be necessary in some cases to keep an Internet connection working.
