IP address for a particular connection in a network can be retrieved by RARP (Reverse Address Resolution Protocol). Your IP address will get changed each time you connect to the network as it is dynamically allocated to your device when it participates in the network. IPv4 address is 32-bit address whereas IPv6 is 128-bit address. If your computer is on two networks so, it will have two IP addresses. IP address is used while routing as it specifically identifies a network connection. IP address identifies both a network and the host on that network. IP address is provided by the administrator of the network or by Internet Service Provider (ISP). IP address does not uniquely identify a device on a network but, it specifies a particular connection in a network. A manufacturers OUI is assigned by the IEEE. The OUI - MAC ADDRESSES, The first 24 bits are known as the OUI (Organizationally Unique Identifier), which identifies the NICs manufacturer. How do manufacturers assign a unique MAC address to each NIC Before manufacturing NICs, every manufacturer obtains a universally unique 3-byte code, known as the organizationally unique identifier (OUI), from the. Which part of a MAC address is unique to each manufacturer A. The address provided to a connection in a network is called IP (Internet Protocol) address. A LAN network does not work unless each device in the LAN network has a unique MAC address. Im taking a guess at my own question: yes, every Ethernet RJ-45 port has a unique MAC address. To ensure uniqueness, every vendor that sells Ethernet devices must register with the IEEE to obtain a unique 6-digit hexadecimal (that is, 24-bit or 3-byte) code called an organizationally unique identifier (OUI). ARP (Address Resolution Protocol) is a protocol used to receive MAC address of a device. All MAC addresses must be unique to the Ethernet device or Ethernet interface. MAC address is used at the data link layer of OSI/TCP/IP model. When you change or replace the NIC card of your computer, your MAC address also gets changed. MAC Address of each computer on a network is unique.

On the other hand, SS:SS:SS is a serial number of NIC card. The format of a MAC address is MM:MM:MM:SS:SS:SS, where MM:MM:MM is a 3-byte address of the manufacturer. A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. The MAC address is provided by the manufacturer of the NIC(Network Interface Card).

It is also called the physical address, or the Burnt-In address, or the software address. MAC address is a 48-bit hexadecimal address. MAC Address(Media Access Control Address) MAC address is the address that uniquely identifies a node on the network. NIC is an interface hardware that is used by the computer to become a part of a network. MAC address is burned into the ROM of Network Interface Card (NIC). MAC address is purchased by the manufacturer, producing interface hardware and assign the MAC addresses sequentially to the interface hardware as they are produced.

Address that uniquely defines a hardware interface is called MAC (Media Access Control) Address. Seeking answers to the question How to find MAC Address on Windows 10 Check out this site to find valuable information about this task and extra details.
