How to locate a device using a MAC address on macOS
#Windows command mac address for wifi windows
Open the CMD (Command Prompt) by writing “cmd” in the search menu, which is at the left hand corner of the screen, next to the Windows icon.How to locate a device using a MAC address on Windows This is how to get that information, step by step, in Windows and macOS.
How to locate a device using a MAC addressĪs previously mentioned, you can use ARP to obtain an IP from a known MAC address. The ARP packet contains a simple question: What is the MAC address corresponding to IP address 10.5.5.1? The host that has been configured to use the IP address responds with an ARP packet containing its MAC address”, as explained in this IBM blogspot. “When a host wants to send a packet to another host, say IP address 10.5.5.1, on its local area network (LAN), it first sends out (broadcasts) an ARP packet. ARP is the protocol used to associate the IP address to a MAC address. So, if you have a device's MAC address, you can find the related IP address of that device using the protocol called ARP, which contains a table that dynamically maps the MAC address with the IP address of every device in the network.Īll hosts on a network are located by their IP address, but NICs do not have IP addresses, they have MAC addresses. So if your computer has both an Ethernet port and Wi-Fi, there will be two MAC addresses in the system configuration Address Resolution Protocol (ARP)Īddress Resolution Protocol, or ARP, is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address, which is a 32-bit number that uniquely identifies a network interface on a machine. For each network interface in the device, there is a unique MAC address associated. They are called the Organizational Unique Identifier, while the last six digits represent the Network interface Controller assigned by the manufacturer.ĭevices can have multiple MAC addresses. The first six digits represent the manufacturer.
This is the way a Mac address is displayed: These 48 bits are represented as a 12-digit hexadecimal number or a six-byte binary number separated by colons.
It implements the physical layer circuitry necessary for communicating with a data link layer standard, such as Ethernet or Wi-Fi. A NIC provides a device with a dedicated, full-time connection to a network. What is a MAC address?Ī Media Access Control (MAC) address is the physical address of a device, which consists of 48 bits, embedded into the Network Interface Card (NIC). So, a device must know the destination MAC address to communicate locally through Ethernet or Wi-Fi. Their frames encapsulate packets that contain IP address information. This will help identify its corresponding IP address.ĭevices in the data link layer depend on MAC addresses for their communication. If you are in a situation in which you can't find the IP address, then you can resort to the MAC address of a device. Also, your computer might be unable to display its IP due to various reasons, and, as a result, you could get a “No Valid IP Address” error. It is worth noting that IP addresses can be masked through Virtual Public Networks (VPNs). Why it might be useful to locate a device using a MAC address

And thanks to that, users are able to access websites without memorizing this complex series of characters.Įach IP packet will contain both the IP address of the device or domain sending the packet, and the IP address of the intended recipient. DNS resolvers translate human-readable domain names into IP addresses. Without an IP there is no way to establish that connection.Įach IP address is a series of characters, such as “192.168.1.1”. The purpose of an IP address is to handle the connection between devices that send and receive information across a network. Every device on a network has a unique address called IP address, which helps identify the device and enables other devices to communicate with it.
