List all MAC addresses and their associated IP addresses in my local network (LAN)


You can use the Nmap utility for this. Nmap is a free network scanner utility.

Try just:

sudo nmap -sn

Please substitute your network identifier and subnet mask.

How to find a network ID and subnet mask

Use command ip a:

bash~$ ip a 1: lo: mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: wlan0: mtu 1500 qdisc mq state UP qlen 1000 link/ether c4:85:08:94:ee:9a brd ff:ff:ff:ff:ff:ff inet brd scope global wlan0 inet6 fe80::c685:8ff:fe94:ee9a/64 scope link valid_lft forever preferred_lft forever

Here at point 2, I have the wlan0 device. It says inet brd scope global wlan0, IP address:, subnet mask: 24. Network ID is, just substitute the last number by 0.

Or as man nmap says:

sudo nmap -sn...

There are times when it can be handy to know which other devices are on your local network. For example, suppose that you need to know whether a certain device (such as a computer, tablet or router) is up and running and responding. If you have a PC or Mac, you can just go to the relevant network setting to see what the IP address is, but some devices such as printers and mobile phones don’t always provide an easy way to do that.

Fortunately, there is a very useful command built into Terminal in Mac OS X called ping that can be used to do just that. Ping can be used either in the command line form, or from within Network Utility, and there are also lots of other free apps which can help you to build up a local network map by way of using the ping command.

This article shows you how to determine the IP addresses of all devices connected to your local network.

If you need to view the IP addresses of other hardware on the same LAN (Local Area Network) as a Mac, the command line arp tool works quite well. You’ll quickly find other devices IP and accompanying MAC addresses, which can make direct network connections easier and be helpful for many other network and troubleshooting purposes.

Find Local Device IP Addresses with arp

To get started, launch the Terminal app from /Applications/Utilities/ (or accessed with Spotlight and Command+Spacebar). The arp tool is uses ARP (Address Resolution Protocol) to display and control network address resolution functions. For the purposes we want to achieve here, the most simple use of arp is with an -a flag attached:

arp -a

This will return devices found on the local network, including other Macs, PCs, routers, iPhones, and iPads, displaying both their LAN IP address as well as their individual MAC address. (For the latter, you can help distinguish hardware by...

A. An easy way to get a list of MAC to IP addresses on the local subnet is to ping every host on the subnet and then check you ARP cache, however pinging every individual node would take ages and the entries only stay in the ARP cache for 2 minutes. An alternative is to ping the broadcast mask of your subnet which will ping every host on the local subnet (you can't ping the entire network as you only communicate directly with nodes on the same subnet, all other requests are via the gateway so you would just get a ARP entry for the gateway).

A list of IP addresses on the LAN will be of limited help, as the issue is there are two machines trying to use the same IP address.

I would suggest that you attempt to find the MAC addresses of the two machines that are clashing.

What device logged the IP address conflict? Was it a server, router, etc.? Some platforms (Solaris and BSD) will log the MAC address of the offending host along with the error message. If the IP address in question is within one of your DHCP pools, it's also worth checking your DHCP server's logs for the MAC address it's attempting to assign that IP address to.

Failing that, I would recommend logging on to the default router of the subnet that this problem is occurring on, and monitoring the ARP table. There should be one IP address that flips between multiple MAC addresses; again, those two MAC addresses represent the devices you are interested in.

Once you have the MAC addresses of the two devices, you should be able to tie...

TCP/IP computer networks use both the IP addresses and MAC addresses of connected client devices. While the IP address changes over time, the MAC address of a network adapter always stays the same.

There are several reasons you might want to know the MAC address of a remote computer, and it's really easy to do by using a command line utility, such as Command Prompt in Windows.

A single device can possess multiple network interfaces and MAC addresses.

A laptop computer with Ethernet, Wi-Fi, and Bluetooth connections, for example, has two or sometimes three MAC addresses associated with it, one for each physical network device.

Why Figure out a MAC Address?

There are numerous reasons to track down the MAC address of a network device:

To set up MAC address filtering on a router to restrict local network access to only those devices whose addresses match a list of presetsTo determine the device's manufacturer (first half of the address) and...

I want to find all IP addresses of devices in the local network I'm currently connected to using Java code. The useful utility Advanced IP Scanner is able to find various IP addresses in my subnet of 192.168.178/24:

According to this answer, I built my code the following way:

import; import; public class IPScanner { public static void checkHosts(String subnet) throws IOException { int timeout = 100; for (int i = 1; i < 255; i++) { String host = subnet + "." + i; if (InetAddress.getByName(host).isReachable(timeout)) { System.out.println(host + " is reachable"); } } } public static void main(String[] arguments) throws IOException { checkHosts("192.168.178"); } }

Unfortunately, this does not print out any results, meaning that no IP addresses are reachable. Why? There are devices in my local network like seen in the Advanced IP Scanner...

Experienced Unix users, look away now, please -- the following is a


simple hint. Over the weekend, I "lost track" of a device on my network. We've got a wireless video camera, but I've had it unplugged for a very long time. I plugged it in this weekend, but couldn't even begin to remember what IP address I'd assigned to it. So I wanted a simple way to just poll my network and see what was out there, which would let me find the camera by process of elimination.

Some versions of the ping command support the -b broadcast flag, which will send a ping request to any device capable of receiving such requests on your network, and report back with the addresses of those that replied. Unfortunately, Mac OS X's version of ping doesn't seem support the flag -- it doesn't work if you try to use it, and it's not listed in the man page. Just as I was about to go find and build a new ping, a much more Unix savvy friend of mine offered this alternative:

I want to get the list of all IP addresses (i.e devices) present in a local area network. I don't want to use nmap, other networking tools. And also I don't want to ping each Ip address in a sub-net range and find live IP addresses? Is there any way by using C, C++?

There is no reliable way to determine all hosts in a LAN. There are many means of guessing your neighbors, each with its own advantages and drawbacks. But you will never be sure you get all hosts. e.g you can try to ping a broadcast, but someone could not reply to the ping. So there is no reliable way to do it. There are some ways which rely on commands in a terminal. You can try using nmap. Although it needs to install nmap:

nmap -sP 192.168.1.*

This does a simple ping scan in the entire subnet to see which all host's are online.

Or you can also try the following steps (Does not require installing nmap):

Type “ipconfig” at command prompt. This will give you ip address of your own machine. For...
