Ping Mac Address For Ip

by

IP is a key source of communication to ping MAC address with local devices to the network, thus every device you have does maintain a local IP address, and the record of Mac Address along with associated IP address is saved in the device and that can be found using some ping options

It is usually not possible for a person to get the MAC address of a computer from its IP address alone. These two addresses originate from different sources. Simply stated, a computer's own hardware configuration determines its MAC address while the configuration of the network it is connected to determines its IP address. I checked the IP, gateway and mask and they are all correct and it's participating in pagp. Now the switch side - we can see the MAC addresses with no issues but can't seem to ping the device on 172.16.21.51 - we understand that historically this was a bitch to setup but we don't remember the actual setup even though we've checked the old.

Here we will be using the address resolution Protocol which is a protocol to find Mac Addresses with IPs in network segments, and If you’re not aware every device in a data link layer depends on Mac addresses to get their communication done.

Know how the ARP command works which do let you the Mac Address by easy options, Mac Address is an important connection that lets you configure and track your device if required.

Every device has its respective IP address with an associated Mac Address which can be found using a pinging option, and here we have a few steps, which you can follow to ping Mac Address in your Mac OS X device.

How to Ping Mac Address

  1. Launch the Terminal by finding it from Apple Menu
  2. It can be found in Utilities under Applications menu
  3. Now enter the arp command in terminal and hit enter
  4. A list of options does show on screen for arp command
  5. Type arp -a command and wait for a second after hitting enter
  6. A list of ARP entries will be shown in the form of a table on screen
  7. Here select your requested IP from the list shown beside Mac Address
  8. Type PING IP address and press enter to see the result of PING
  9. The output of the IP address, Mac Address, interface, and the allocation type will be shown on screen, which makes it easy to find the IP address and Ping it on a Mac device.

Is it possible to Ping a Mac Address?

The Address Resolution Protocol tool is prepared to ping a Mac Address using the ARP packets in your LAN, and this tool does get you a list of Mac Address associated with respective IPs during its execution.

Can a device be found using its Mac Address?

Go to settings under Wireless & Networks to find the Wi-Fi option, here tap on the advanced button to open the Wi-Fi options screen, and at the bottom of your page, the Mac address and IP address will be displayed on the screen.

Is Using ARP command safe to Ping Mac Address?

Address Resolution Protocol is a command which shows its output when you enter arp in Mac terminal, and this is an inbuilt command which collects the data of IP addresses and their associated Mac Address from Mac devices with also listing their location type.

Is a Mac Address traceable?

The Mac Address is only traceable when it is being connected to a network and shown as active, and If your Wi-Fi connection has been logged in by different computers then you can view the Mac Address of that connected computer, Else it is not possible to get a trace of Mac Address of any device directly.

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.

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.

I hope this guide was helpful for you. If you aren't sure about something or feel like I missed a step, please let me know.

    Great 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 | i

    Download virtual во with crack for mac. This will give you the port that the device is currently connected.

    Thanks 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?)

    Good stuff, thanks for posting this! My go-to Cisco command is: show ip interface brief (show ip int bri). Another thing I've learned that is very helpful (I'm still a noob with Cisco stuff) is tab-completion and using a '?' after the start of a command, such as 'show ?'

    Unfortunately 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.

    Spiceworks 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.

    Couldn't you just use CDP? #show cdp nei detail will show you the ip of the connected devices.

    Hey 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.

    Keep 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.

    Great info.

    Another helpful thing you should add!

    SHOW INVENTORY ---> To show the SERIAL number of the Cisco device you are on. Webdav mac os x.

    **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!
