Apple Inc.'s Mac computers incorporate a wide range of keyboard commands designed to access functions in Mac OS X Snow Leopard and Macintosh applications. These commands reduce your need to rely on a mouse, trackball or other input device to operate your computer. Most commands involve the use of one or more modifier keys in addition to a character key.
At the command prompt, type 'ping ' and press Return. Most Windows commands will work in OSX by simply pressing 'command' instead of 'control'. For example, ctrl+v (paste) ctrl+c (copy), ctrl+z (undo) and ctrl+a (select all) still all work on a Mac, just replacing the control key with the command key. 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. Mac OS X is built on a version of Unix called Darwin. To access the Unix command prompt in Mac OS X, open the Terminal application. It is located by default inside the Utilities folder, which in turn is inside the Applications folder. For information about Unix commands, see Introduction to Unix commands. This infromation was quoted from here.
Command Keys
The 'Command,' 'Control,' 'Option,' 'Shift,' 'Caps Lock,' 'Function' keys (on desktop and notebook systems) and the 'fn' key (on notebook computers) all are modifier keys. By themselves, these keys usually do not perform any functions, though pressing them may wake your computer from sleep mode or deactivate a screen saver on your monitor. All key combinations require you press at least one of these modifier keys. Some combinations use two or three modifiers.
Character Keys
Character keys include letters of the alphabet, numbers and punctuation. Many key combinations rely on character keys with a direct, mnemonic (easy-to-remember) relationship to the task performed by the command. For example, Command-P invokes the printing process; 'Command + O' opens files; 'Command + C' copies selections; 'Command + Q' quits many applications. Not all key commands offer the mnemonic potential of these examples, but since many processes and operations share letters of the alphabet, the most-used ones tend to acquire the simple shortcuts.
'Dead-Key' Combinations
These special command sequences enable you to type accented characters into a word processor or text field. The term 'dead key' refers to the fact that in most circumstances, the key sequence requires two parts and produces no results until the second part is complete. For example, you press 'Option + E' and release those keys, then type another vowel to produce that second vowel with the acute accent, which is used to indicate emphasis or pronunciation in many languages.

Resolving Command Variance Among Applications and Your Operating System
Just because the Macintosh operating system assigns specific functions to certain key combinations doesn't mean you can't reassign them. Go to your 'System Preferences' and choose 'Keyboard Shortcuts' to change the results of specific keyboard commands, add your own shortcuts or override a command assigned in the operating system that performs a different function in an application you use frequently.
Migrating to the Macintosh Operating System
If you're new to the Mac, you'll need some time to acclimate your fingers to reaching for the 'Command' key instead of the 'Ctrl' key. That's because the two operating systems share many simple commands that differ only in the modifier key they incorporate. Think 'Option' instead of 'Alt' and remind yourself the Mac has a 'Control' key in addition to its more-frequently used 'Command' modifier. Many Macintosh-compatible USB keyboards show both versions of these key names to ease your migration and provide an at-a-glance reference.

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
Thunderbolt external drives. 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.

- DatilKrizz Jan 21, 2013 at 10:36pmYou'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 11:24pmPublisher for mac free. 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 03:17pmI'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 04:37pmI 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.
- Pimientochristian.mcghee Dec 23, 2013 at 03:47amThis 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 03:11pmI 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.
- Pimientochristopherblouch Jun 4, 2014 at 05:08pmI 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 10:07amGreat 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.
- Pimientorobertrobinson2 Aug 4, 2014 at 04:30pmI 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 01:05pmThis 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 01:12pmBy 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 03:28pmUse SuperScan to do a bulk ping of the entire network range. SuperScan 3 (I recommend) is a free tool by McAfee. https://igmiapg.weebly.com/blog/gameboy-advance-emulator-for-mac.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 07:55pmThere'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.
- Pimientoamiruli Jul 4, 2015 at 10:18amIf you want you can ping the broadcast address to ping everyone on the network then do arp -a
- Pimientochrisdahlkvist Nov 23, 2015 at 09:56am@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.Chris Dahlkvist
