Get device mac address linux8/25/2023 In the output, you will receive the ARP reply from the destination system containing its MAC address. If your system has multiple NICs, you can specify from which interface a request should be sent using the -I flag (capital "i") followed by the interface name: sudo arping -c 1 -I interface_name įor instance, the following command will send one ARP request from its ens33 interface to the remote system's IP address 192.168.42.133. Once installed, find the MAC address of another system on a network by specifying its IP address as an argument using the following command: sudo arping -c 1 The output will display the MAC address for all the network interfaces. On RHEL-based distributions: sudo yum install arping Type ifconfig -a or ip link show or cat /sys/class/net//address command Press Enter to run the command. ![]() But is there any set of options on these commands (or any other command) that can tell me the actual device name of the device at a give IP For example, if 'Joe's iPad' is on 192.168.1.113 I want a command to get that name. On Debian-based distributions: sudo apt install arping I also know that arp-scan will do a MAC address lookup to get the device manufacturer. You can install arping using the following commands: It is different from the ping utility which functions at the third layer. It functions at the second layer in the OSI model and sends the ARP request to the system to determine whether it is alive and responding. The arping utility helps you discover and probe local systems on a network. Like IP addresses, you can also change the MAC address of your NIC. MAC address functions at the second layer (Data Link layer) of the OSI model and is 48 bits in length, where the first 24 bits represent the manufacturer ID and the last 24 bits represent the unique ID for that NIC. What Is a MAC Address?Ī MAC address, also known as a physical or hardware address, is a unique identifier associated with a network interface card of pretty much every device connected to a network. Whatever the reason is, here are a few different ways to find the MAC address on your Linux system. You may also need this information for MAC address filtering to allow or block certain devices on your network. For this, you will need the MAC address so that you can add the IP and MAC address mapping to your DHCP server configurations. 1 Answer Sorted by: 23 Execute the following command line in macOS: systemprofiler SPBluetoothDataType The output will print details about the build-in Bluetooth device along with the MAC address. ![]() Perhaps you want DHCP to assign you a fixed IP address. You may need this information for several reasons. If you are administering a Linux system, there will likely be times when you need to know your system's MAC address.
