Sudo arp-scan -interface eth2 -l - You can also limit the scan to a rango of ips e.g. Starting from 192.168.1.1 to 192.168.1.100 with this command. Sudo arp-scan 192.168.1.1-192.168.1.100. Still can't connect to the device even though the ip is right? Sometimes the remote management surface must be accessed using a special port and most of.
Choose a subnet from the Local Subnet combo box and click the Start button or F5 to execute scan. Colasoft MAC Scanner will display scan results in the list, including IP address, MAC address, Host Name and Manufacture. It will group all IP addresses according to MAC address if a MAC address is configured with multiple IP addresses. Using -plain option of arp-scan can make things easier. It will display plain output showing only responding hosts. The hosts' information are separated by tab, MAC address (2nd column) can be extracted easily through cut, as Anony-Mousse described: arp-scan -l -plain cut -f 2. Destaddr= or -T Send the packets to Ethernet MAC address This sets the 48-bit destination address in the Ethernet frame header. The default is the broadcast address ff:ff:ff:ff:ff:ff. Most operating systems will also respond if the ARP request is sent to their MAC. $ arp-scan -interface=ens3 -localnet Specify Network Interface Set Source Mac Address. During the scan process our exisiting mac address will be used. This may create some clue about the scan. We can change the source mac address during scan. This will make all sent packets have different mac address than our hardware mac address.
How to find an IP address when you have the MAC address of the device.
4 Steps total
Step 1: Open the command prompt
Click the Windows 'Start' button and select 'Run.' In the textbox, type 'cmd' and click the 'Ok' button. This opens a DOS prompt.
Step 2: Familiarize yourself with arp
Type 'arp' in the command prompt. This gives you a list of options to use with the arp command.
Step 3: List all MAC addresses
Type 'arp -a' in the command prompt. This lists a number of MAC addresses with the associated IP addresses. Since you have the MAC address, scroll down the list to find the associated IP address. The MAC address is shown in the 'Physical Address' column with the IP address in the 'Internet Address' column. An example of a table record is in Step 4.
Step 4: Evaluate results
The following is an example of ARP output. The first column is the IP address. The second column is the MAC address, and the third is the type of IP assigned--static or dynamic.
Internet address Physical Address Type
192.168.0.1 01-a3-56-b5-ff-22 static

You've forgotten about one little thing: arp keeps mac<>ip association of recently contacted peers, so it's quite often not to find the mac<>ip association we're looking for, of machine that exists in the network. Prior to using arp -a it's wise to ping the host first.
- HabaneroTwon of An Jan 21, 2013 at 11:24pm
Used in conjunction with ping (thanks Krizz), this is a good basic walk through. I can't go wrong with these steps!
- CayenneSyldra Jan 22, 2013 at 03:17pm
I'm sorry but.. if the thing is to find the IP address from the MAC, how will you ping the host first ?
- SerranoEnzeder Jan 22, 2013 at 04:37pm
I thought the aim of this exercise was to FIND an IP address. Doesn't using PING imply you already know the IP (or hostname) which makes ARP redundant? How do you PING a MAC?
Assuming no IP or hostname info, I have used a portscanner (like LanSpy or Zenmap) to get MAC > IP info. Currently my preferred method if the device isn't listed in Spiceworks :-)
There was a time when I was a baby admin and I didn't want to raise alarms by installing a scanner that I wrote a batch file (yes, that long ago) that PINGed every IP on a subnet, then immediately ran ARP redirecting output to a text file. But that depends on the device in question being set to respond to PING requests.

This does not work for any host on the other side of a router. Any hosts on the other side of the router will show the routers MAC address.
- Serrano@Greg Mar 11, 2014 at 03:11pm
I realize this is an old topic, but someone like myself may be looking for an answer. I became admin of a network with little over 200 devices, which none of the cabling was mapped. I was told I was responsible for the cabling, so I began looking for a way other than toning out all the cables. I was fortunate to have Cisco switches and Windows Server 2008. I was able to use the Cisco Network Assistant to grab MAC addresses and the port number, then in DHCP on the Server 2008 I could find the MAC and corresponding IP. Furthermore I could also get the computer name from DHCP and correlate that to which user was on the machine using PDQ inventory to see who was logged in to the machine. Most of this of course depends on the devices being in use. I've been able to create an accurate map of about 90% of my network without touching the cables.

I am interested in this thread, hopefully someone can help. There are 4 types of arp message: arp request, arp reply, rarp request, rarp reply. So, that being said, is it possible to manually send a rarp request? Sort of a arp based ping?There is arping, but we need rarping.. if it exists. Of course, I understand that I can't arp outside my default gateway, but if there is a rarp request, how is it used inside the local network? Thanks to whatever guru can explain what we're missing.
- SerranoMaxwell Brotherwood Jul 18, 2014 at 10:07am
Great for finding an IP if you have the MAC address.
My instance where I found this useful was after updating the firmware on a switch remotely via TFTP, the IP of the switch would change (making pinging redundant, obviously). Trying a network scan over Spiceworks or rescanning the single device would not update the IP and I needed an alternate way to find it.
This method worked perfectly. Thank you. Hopefully this helps those trying to understand the purpose of this practice and how it was in-fact useful.

I understand the issues in attempting to use a MAC address to locate a device from outside of its local network.
What puzzles me is how Honeywell Total Connect does this with their WiFi connected thermostats. The hardware configuration is: a Honeywell WiFi thermostat that is WiFi connected to a Netgear N600 router which uses DHCP to assign an IP adddress. The router is connected to Comcast with a Motorola SB6120 modem. Comcast assigns a system wide (dynamic) IP. There is no static IP.
On initial setup, a WiFi connection is first established between the thermostat and the router. The thermostat's MAC and CRC and a username and password are entered into the Total Connect software setup. It is then possible to read or set thermostat values using Total Connect Web pages.
I know how to do this with a static IP or a DNS service that automatically tracks changes in dynamic IP addresses.
Does anyone understand how this works with Total Connect? - TabascoJoe979 Sep 4, 2014 at 01:05pm
This post was extremely helpful, thanks itdownsouth :) I used show interface to find MAC addresses on our switches (reason for this is poor network documentation and mis-labeled switchports and wall jacks..). I took the MAC addresses that I could not locate the hosts or ip addresses for, ran arp -a to list the address<>mac list, then one by one, nbtstat -A for each IP address I matched a MAC to from the unlabeled ports. Tedious, but found 5 or 6 now (seeing hexadecimal thoughts now though..).
- TabascoJoe979 Sep 4, 2014 at 01:12pm
By the way, the reason this is working great for me is the lack of routers -- all switches, so if you have only one subnet like we do, this will do -- otherwise, you will probably need to login to the router or switch on the other side of the router to find MAC address tables on the other networks. You may not be able to see them all on the local host, as far as arp -a on the local host, but looking up the arp or hosts tables on switches and routers could be a possible solution for those with multiple subnets.
- JalapenoJay196 Oct 21, 2014 at 03:28pm
Use SuperScan to do a bulk ping of the entire network range. SuperScan 3 (I recommend) is a free tool by McAfee.
Then use arp -a | Find '5c-d9-98' to get for example all ping nodes with a manufacturer of Asus.
- DatilWealthyEmu Mar 25, 2015 at 07:55pm
There's also this:
http://www.advanced-ip-scanner.com/
It should be able to find most devices on the network. You can specify the range to scan and scan across subnets. I won't try to share all the features because quite frankly I don't know them all.

@RobertRobinson I'm the lead designer and project manager on the Honeywell systems.
I can tell you exactly how I designed it. It's actually quite simple. Nothing is sent back to the unit. The unit is allowed access to the Internet via your setup and the router. As long as the unit has permission to make an outbound connection it will work. What happens is the unit makes a report to the server. If it needs to make a request then it gives the server a unique key. The server puts any needed data in an xml (readable) and the thermostat (or quite a few other devices) hits that URL a few seconds later (the device told the server where it would pick up that info).
All your device needs is a simple read-only connection to the outside world. No need to download anything.
It's a VERY simple process that I developed back in 1992 when the Interwebs were still pretty new to most people. There were many processes built off of this simple idea (it was pretty cutting edge when I first designed it). Store and forward, offline browsing, push technology, etc. all are based on this simple technology.Am I rich? Not even close. I was working on my PhD at the time and was hired by Honeywell to implement my design. I literally gave it away to the general public as is right.
I hope that clears it up for you. If not, feel free to contact me for more information.

Network scanning is a necessary task, but it can start off simple and rapidly become more complicated as your business gets larger. Manually finding IP addresses on your network is possible, but why do it yourself when there are so many tools to help you? Not only can network scanning tools help you find IP addresses, but they can also provide extra information for monitoring, troubleshooting, and keeping your network running efficiently.
My top choice for a network scanning tool is the SolarWinds® IP Address Manager, as it works in an intuitive and easy-to-use way while offering a broad suite of tools and functions. It's more approachable than some of the other tools out there and has a flatter learning curve for figuring out how to get started.
How to Find IP Addresses of Devices on My Network
Curious how to find IP addresses on-network? You may need to know about either static or dynamic IP addresses. If you can access your router, you may be able to simply view the client lists and get information like hostname and MAC address. Or you can use a device connected to the network to ping the network and view the ARP tables. Done manually in this way, you have to do everything through the command line. Use the prompt 'ipconfig' on Windows to get network settings, followed by 'arp -a' to view IPs plus MAC addresses.
However, this method doesn't work across subnets. This means that if you have multiple subnets on your network, you have to go through each individual router or subnet to determine the IP addresses within the subnet. It becomes pretty clear as your network scales, manually scanning for IP addresses becomes an extremely complex task. Multiple subnets and an ever-changing string of devices connecting to and disconnecting from the network becomes problematic.
Instead of attempting to manually manage these aspects of your network, I recommend using an IP address manager (IPAM). These tools help you to manage your IP addresses and troubleshoot problems, but they also help you to find all the IP addresses of the devices on your network and determine the status of each one (dynamic, static, available, reserved, etc.). Some tools will also integrate with DNS and DHCP, and all of them will usually present data in a visual, interactive format. Many also allow you to save your network scanning results and present them in spreadsheets or reports.
Best Network Scanner Tools 2020
SolarWinds IP Address Manager
This is my top choice for network scanning software. The SolarWinds IP Address Manager (IPAM) with its IP Address Scanner feature is great for both beginner users and small businesses, and expert network administrators and large enterprises. With automated IP address tracking and integrated DHCP and DNS management, you can quite easily monitor your IP addresses and associated network information.
You can also see all your subnets and how they are structured, and which subnets and scopes don't have much free space remaining. It allows you to flag capacity issues before they become a problem so that IP address issues don't affect performance. I've also found it's easy to find unused IPs and reclaim them to tidy up my networks.
This IPAM uses a clean and simple interface, without a steep learning curve like some other IP address managers. You can easily assign management or control permissions to other admins or admin groups, allowing you to delegate tasks simply within the IPAM rather than needing to use another tool. The console is centralized, allowing you to see all the relevant information in one place, reducing the potential for error.
I consider the SolarWinds IPAM to be a complete solution, and it's my choice for an all-round lightweight tool you can use to scan and maintain your network. There's a free trial available so you can try it out, then level up to gain access to more features and greater scalability.
MyLanViewer
This is another strong business-level contender for network scanner tools. MyLanViewer is an IP and network scanner, as well as a traceroute tool and network monitor. It uses a buddy-list style window to display all of your network computers, including important technical information about each one. It can scan your network to monitor IPs and let you know when any details change. It also supports remote shutdown and other remote functions for each network computer. It can monitor hidden devices on your subnets and discover bottlenecks in your connection with its traceroute tool. I'd say this is a fine choice for business use—it has an easy-to-use interface and is suitable for beginners and advanced users.
Angry IP Scanner
Looking for one of the best free tools? This is an open-source and free network scanning tool, with the ability to scan ports and IP addresses quickly and efficiently. The tool provides a report of data on each device on the network, including NetBIOS, MAC and IP address, computer name, and hostname. Keep in mind that open-source tools do require a bit more know-how on the user's part and aren't my usual pick for business use.
Angry IP Scanner can also produce reports in XML, CSV, and TXT format, which is useful for exporting data and other things within your business. Its unique feature is it uses a multi-threaded scanning approach, which uses a separate scanning thread for each IP address. This helps to improve the scanning process and make it more accurate.

Picking the Best IP Scanner
Arp Scan Tool
When I want to discover IP addresses on my network or scan for data generally, I tend to lean toward using a network scanning tool rather than trying to do it manually. Many network scanners have simple interfaces, and some go above and beyond in terms of ease-of-use and clean interface appearance. I like using the SolarWinds IP Address Manager, as it contains a pretty hefty solution in a lightweight package, with a free trial for people who want to try it out without commitment.
