For example, if you have a group of offline computers on a network, they will communicate with one another through internal IP addresses, which always have the IPv4 format.Įxternal (public) IP addresses are assigned by your internet service provider (ISP) when you first go online and hook to a device or network that connects to the internet. In the example above, XXXXXXXXXXXX and YYYYYYYYYYY are the MAC addresses of the two LAN connections in use.Before you find your Mac IP address, it’s important to know the difference between the two kinds of IP addresses - internal and external.Īn internal IP address (local or private) is only used within your home network and always for a single device. The second line indicates the type of link layer in use and the current hardware address (MAC address). The first line summarizes the device's current name, the flags set on the device, MTU (Maximum Transmission Unit), etc. For each device, there are two lines summarizing the link state and characteristics.
The ip utility will list a few parameters of the device. Launch Terminal and enter the ip link command: ip link showĮxample results: 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp1s0: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether XXXXXXXXXXXX brd ff:ff:ff:ff:ff:ff 3: wlp2s0: mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether YYYYYYYYYYYY brd ff:ff:ff:ff:ff:ff 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp1s0: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether XXXXXXXXXXXX brd ff:ff:ff:ff:ff:ff 3: wlp2s0: mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether YYYYYYYYYYYY brd ff:ff:ff:ff:ff:ff 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp1s0: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether XXXXXXXXXXXX brd ff:ff:ff:ff:ff:ff 3: wlp2s0: mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether YYYYYYYYYYYY brd ff:ff:ff:ff:ff:ff 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp1s0: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether XXXXXXXXXXXX brd ff:ff:ff:ff:ff:ff 3: wlp2s0: mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 link/ether YYYYYYYYYYYY brd ff:ff:ff:ff:ff:ff Every PC's network device needs a unique MAC address.
