Click the CMD program. In the Command Prompt window, locate Ethernet adapter Local Area Connection. The 12 digit Physical Address (a.k.a. Ethernet Address) will be visible directly below the Ethernet adapter Local Area Connection.
The MAC (Media Access Control) address is a devices hardware address. Each device on a local area network must have a unique MAC address assigned. The MAC address is often referred to as the Ethernet Address on an Ethernet network. They are in fact the same thing.
The MAC address is different unique for the separate Wi-Fi and Ethernet connections, so be sure to give the network administrators the correct MAC address based on how the device will be connecting to the network.
In a LAN, each node is assigned a physical address, also known as a MAC/Ethernet address. This address is unique to each of the nodes on the LAN and is 6 bytes (48 bits) long, which is burned on the Ethernet card (also known as the network interface card). Ethernet is a byte-count protocol.
Ip Address is changeable while ethernet is not. Ethernet is also called as MAC address(Media Access Control). Ethernet is physical address while Ip is logical address.

Source Address – This is a 6-Byte field which contains the MAC address of source machine. As Source Address is always an individual address (Unicast), the least significant bit of first byte is always 0. Length – Length is a 2-Byte field, which indicates the length of entire Ethernet frame.
To ensure a unique MAC address, the first half of the address identifies the manufacturer of the card. This code is called the organizationally unique identifier (OUI). Each manufacturer assigns a MAC address with its own OUI as the first half of the address.

How does ARP resolve an IP address to an Ethernet MAC address? When ARP needs to resolve a given IP address to Ethernet address, it broadcasts an ARP request packet. The ARP request packet contains the source MAC address and the source IP address and the destination IP address.
The initial 0x indicates that it is a hexadecimal number (base 16). The last four digits are the number in base 16. e.g. 0x0001 is the same as 1 in decimal and 0x0800 is the same as 16 x 16 x 8 = 2048 in decimal.
Answer According to the Figure 2, the hex value of this field is 0x0800. It corresponds to the IP protocol. the HTTP response code) appear in the Ethernet frame? Answer According to the Figure 2, the O in OK appear 52 bytes in the Ethernet frame.
It's because they are different connections. Each interface, hard wired or wired, will have its own IP address. The IP itself is assigned by your router. If you are concerned with what pool your IP is assigned from, you need to go into your setup utility and see what is allocated for wireless, and what is wired.
What is the difference between Ethernet and Ethernet IP?
Note that Industrial Ethernet, and particularly EtherNet/IP, differs from standard Ethernet; the most important difference being real-time efficient communications. Ethernet and TCP/IP directly provide this, while EtherNet/IP does in conjunction with a managed switch based infrastructure.
