Ethernet devices are identified by their MAC address, not an IP address. If their were no MAC address incorporated into the device then it is not following the rules define for the ethernet protocol. It would not be an ethernet network adapter or it would be a defective ethernet network adapter.
As the LANs are designed for arbitrary network layer protocols, not just IP, so if the adapters are assigned with IP addresses rather than MAC addresses, than it will be difficult for adapters to support other network layers. Even if the adapters use entire network layer addressing schemes, they will need to be reconfigured every time they are powered up. So it is imperative to use neutral MAC address independent of network layer addressing schemes in order to ensure better performance of network.
802.11 use MAC addresses, which are the same as IP addresses in some networks
Routers don't use MAC addresses for routing. They use IP address.
MAC address are hard coded on network cards and network devices. A HUB acts as a splitter, so yes. >both Mac addresses are provisioned; Implies your ISP will assign unique IP addresses. The hub then acts as only an electrical connection box. Without Unique IP addresses, you need a router instead of a hub or switch
Sometimes a router has the option to exclude all connections apart from certain specific devices. It is those devices' MAC addresses that you will need to enter in order for the router to indentify them.
No. The switch itself will only have one MAC address. Only routers use different MAC addresses for each port.
For network devices, it's a MAC address. MAC stands for 'media access control' and it's a unique identifier that's present in all hardware that interfaces with a traditional computer network. The device that manages DHCP (or assigning IP addresses to devices) often asks the devices for their MAC addresses and then gives them an IP address. Usually MAC addresses are written as something like 00:0a:5e:1a:8d:a2 and they use hexidecimal notation (allowed numbers 0-9, and letters A-F).
Media Access Control (MAC) address filtering is a little different from WEP or WPA. It doesn't use a password to authenticate users - it uses a computer's physical hardware. Each computer has its own unique MAC address. MAC address filtering allows only machines with specific MAC address access the network. You must specify which addresses are allowed when you set up your router. This method is very secure, but if you buy a new computer or if visitors to your home want to use your network, you'll need to add the new machines' MAC addresses to the list of approved addresses.
I think you are mixing up two different protocols. IPv6 addresses are not hard coded into your adapter; MAC addresses are. It's totally different. IPv6 addresses are 16 bytes long and MAC addresses are 6 bytes long.
to determine which ports are not correctly configured to prevent MAC address flooding
They are not always compatible. There are minimum hardware and software requirements. It is possible to use adapters and upgrade hardware in order to make them compatible.
When you connect your computer to a switch, it will automatically detect your computer's settings and will also gather system information, part of this information collected is your MAC address. Every network interface card (NIC) has it's own unique MAC address, and most computers these days have NIC's already installed.
MAC address is fixed to the hardware device (for example a network card) and can not be changed. IP address is assignable. The default IP address for a device can be computed by converting the four right-most numbers of the MAC address from hex to decimal.The MAC address refers to the physical address assigned by the Network Interface Card manufacturer. Example - 10.03.d5.f3.45.fc , where are an Internet Protocol address is given to a computer when it gets connected to the network. Its divided into four parts , separated by fullstops.
