If you've connected the two only to each other, all frames (packets) you can see in your capture should have only one of two source MAC addresses: the one of your PC and the one of the blackbox. So apply a display filter
(eth.src bl:ac:kb:ox:ad:dr) and arp
and if any packets remain in the list, they must have been sent by the blackbox, and they read, in the info column, Who has X.X.X.X? Tell Y.Y.Y.Y
. And Y.Y.Y.Y
is the IP of the blackbox.- Apr 17, 2019 Steps. Open your Android's Settings. You can swipe down from the top of the screen and tap, or you can tap in your phone's app list. Tap About Phone. It's at the bottom of the settings menu. If your Android device is a tablet, this option will say About Tablet instead.
- Feb 26, 2012 if you mean physical location using the MAC address to find a device isn't practical at all, unless that device is on your local network then you wont be able to find it at all and if it is on you local network then the best you can do is find its IP, which still wont give you the physical location.
- There you have the association MAC IP address. You the can use tools like nmap/zenmap to gather more information. If you are just after locking him/her out of your network it may be possible (depending on your router) to block access for the device with the specific MAC address.
For the miracle to happen, you need that the blackbox feels a need to send something somewhere, or read something from somewhere, otherwise you are out of luck because it won't have any reason to send the ARP request you need.
A hint: don't connect them directly, insert a hub or switch between them, and use the following order of steps:

- connect only the PC to the switch and wait until the interface comes up
- start capturing with no capture filter
- connect the blackbox to the switch (and switch it on of course) and do whatever is necessary so that it would attempt to send or receive data.

The reason to do it the above way is that you normally cannot start a capture on an interface which is down, and the frames you need might come between the moment the interface came up and the moment you've started the capture if the blackbox doesn't have much to send/receive.
Knowing the IP address, you'll still have to guess the mask, as it cannot be determined from the ARP requests nor anything else normally seen on the wire. So your best choice is to set
Y.Y.Y.(Y+1)/255.255.255.0
(except if the last byte would make 255, in that case use 253 instead) as the address/mask of your PC's interface and try to log in.If you cannot catch any ARP request, Wireshark cannot help you and you'll have to use some scanning tool which will send arp requests to the device's MAC, asking for all possible IP addresses one by one.
Learning has never been so easy!
As a Network Administrator/Engineer you may be asked to find MAC addresses and/or IP Addresses, hopefully this can make your job a little bit easier. These commands work on most Cisco Switches and Routers but sometimes the commands can vary from device to device.
5 Steps total
Step 1: Connect to your Cisco Devices
Connect to the Switch/Router by using a console cable or a terminal emulator like Putty or Secure CRT. If you are successful it should look something like this.
Step 2: Find The MAC Addresses
On the layer 2 device (switch) enter the username and password if needed. Next enter 'enable' mode on the switch by typing enable. Next type the command 'show mac address-table'. If successful it should look like the picture. It's worth noting that on some Cisco devices the command 'show mac-address-table' also works.
Step 3: Find the IP Address
On the layer 3 device ( L3 switch or router) in my case I am using a router, enter the username and password if needed. Next enter 'enable' mode on the router by typing enable. Next type 'show ip arp' if done correctly you should get an output similar to the picture. Mcculloch pro mac 605.

Step 4: Filtering the results on a Router
In the example I have provided there were only 9 IP addresses. However in the real world there could be dozens or even hundreds of IP addresses. To help filter the results on a router type 'show ip arp ?' You will see gigabitethernet' as an option this will let you filter results by interface or sub-interfaces. In my exmaple it typed 'sho ip arp gigabitEthernet 0/0.10' and that listed all IP's on my sub-interface.
Step 5: Filtering the results on a Layer 3 Switch
As stated in Step 4, you will likely have more than 9 IP Addresses. This can be made worse in a messy closet with a 48 port switch running the closet and maybe even some layer 2 switches under that. Luckily in addition to being able to filter by interface you can also filter by VLAN. So type in 'show ip arp ?' and you will see 'vlan' as a listed filter. As you can see I typed in 'sho ip arp vlan 20' and it listed only those IP's in vlan 20. In this case it was the vlan interface and a PC.

- AnaheimGDBJNC Apr 27, 2018 at 01:15pmGreat post.Another way to find that information is to first PING the address of the system you are looking for. Then issue:
show arp | i .This will then show you the MAC address associated with the IP address.Then issue:
show mac address-table | iThis will give you the port that the device is currently connected. - TabascoJim6795 Apr 27, 2018 at 01:15pmThanks for posting this *after* I finished a 'What's Connected Where' jihad on our network. :^D After beating Google to death over it, hoping for some useful tool, I ended up using exactly the same process (plus the online MAC address lookup to ID the device manufacturer), so I can affirm this works perfectly, if you work it.As you can see, the 'sh arp' or 'sh ip arp' commands also give you the MAC addresses, so essentially the 'sh mac add' is only to get the port in which the device is connected. It helps to Ping the subnet's broadcast address (e.g. '10.1.1.255') to load the ARP table. (Small tip: When you see a large number of MAC addresses showing up on a single port, there's a switch on that port into which those MAC addresses are connected. If you're all Cisco, 'show cdp neighbor' (or 'sh cdp nei') will get you to the next switch. Also, 'sh ip arp | i 0/24' will show just the MAC address(es) on that port.)The amazing thing to me is, this far into the 21st Century, this is still the only way I could find to get this information -- i.e. to find out what's connected where. Did I mention it's a *lot* of work?(ETA: What if you can't get to the Console port? How do you get the IP address of the switch in order to SSH or (if you must) Telnet in?)

- TabascoEd Rubin Apr 27, 2018 at 03:09pmUnfortunately dumping the mac table and working through it is the only way to reliably find stuff and identify its switch port. I've done a similar process with HP switches. One thing that helps a lot is an ip scanner application that does MAC vendor ID lookups for you. This can help with jim6795's problem of identifying an undocumented switch IP since you can look for the the switch maker's vendor ID and then try ssh or telnet, or http/https depending on the product.
- JalapenoTS79 Apr 27, 2018 at 06:53pmSpiceworks has the ability to harvest this information using SNMP and will create a map showing which device is on which switchport. It must have the correct MIB installed for your switch and you must configure SNMP. The feature could use some more work but basic components are there.

- Thai PepperTaylorC Apr 27, 2018 at 08:45pmHey everyone thanks for the great feed back, it's really cool having this featured. @SadTech0 if you cant to the console port and you don't know the IP Address you could use a tool like angry IP scanner and find the switch that way. CDP may or may not work depending on your network configuration and/or topology. Barring some major obstruction you should try to console in get the ip and start an inventory. Hope that helps.
- Thai PepperTodd_in_Nashville Apr 30, 2018 at 12:34pmKeep in mind, in some security minded environments, CDP may be disable if it's not needed. It's one of those things that give out unnecessary reconnaissance info to the bad guys. If one of your edge routers gets compromised, it can be used to start footprinting your internal network.
- Thai PepperJohn3367 Apr 30, 2018 at 08:51pmGreat info.Another helpful thing you should add!SHOW INVENTORY ---> To show the SERIAL number of the Cisco device you are on.**I always use those commands you show to troublshoot. They are very helpful. I usually PING an IP address. then I type a 'show arp' and get its MAC address. then I will type 'show mac-address table' which will show me which PORT the device is connected to!
