When your computer connects to the internet, it has a unique number assigned to it called an Internet Protocol (IP) address. Similar to a mailing address, each computer on the network has a dedicated IP address that identifies it. Without an IP address, no messages or information packets can be sent or received.

You should be wary — if someone knows your IP address, they may be able to hack your computer or find you via geolocation data. Although to actually pinpoint your location they would need information from your ISP provider that’s only accessible with a search warrant.
MAC Address can be located on networking card box or through the operating system after it installs in computer. You can view your networking card MAC Address by typing ipconfig /all in command prompt in any windows version, and the field 'Physical Address' actually indicates your networking card MAC Address. Type that address here to look it up. Here, it shows IP addresses for various interfaces installed on the computer, it includes IPv6 interfaces as well. If the system is connected to a DHCP configured network then you can release the IP obtained from DHCP. Ipconfig /release. The above command works for IPv4. To release IPv6 address the command is given below. Ipconfig /release6. 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. Click the 'Start' button the click the 'Run' box (if using Windows XP) or 'Search' box (if using.
So if you want to fix a network access problem or set up certain types of software, sometimes you might need to search for “how to find my IP address on Mac”. Luckily, there are a few simple and quick ways to find your IP address or change IP address on Mac by using a VPN. Let’s break this down step by step.

How To Find IP Address On Mac
Before you find your Mac IP address, it’s important to know the difference between the two kinds of IP addresses — internal and external.
An internal IP address (local or private) is only used within your home network and always for a single device. For example, if you have a group of offline computers on a network, they will communicate with one another through internal IP addresses, which always have the IPv4 format.

External (public) IP addresses are assigned by your internet service provider (ISP) when you first go online and hook to a device or network that connects to the internet. Usually, when you need to find your Mac IP address it means an external one, but you’ll learn how to check both in the explanation below.
MAC Address vs IP Address difference
A MAC (Machine Access Control) address is a serial number assigned to every network adaptor. Your computer’s network adaptor MAC address travels the network only until the next device along the way. This means that your MAC address won’t go further than your router and is less at risk of being hacked. So when you’re looking to change IP address on Mac to protect your network, you’ll need to watch for your IP address rather than your MAC one.
Find Ip Address Using Mac Address
How to check IP address on Mac: external (public) IP address
What is the process you would follow to find your IP address on a Mac computer? The method you use to find your external IP address will depend on whether you’re connected via a router or directly to the modem.
In the rare case that you’re connected to the modem via an Ethernet cable, find IP address on Mac with these steps:
- Open System Preferences by clicking the Apple logo dropdown menu
- Choose Network
- Highlight the option on the left with a green dot. On the right, it should say Connected and show you the IP address right under.
If you’re connected to a router, you can try a few other options on how to find IP address. First is to use a special service such as What’s My IP Address? Alternatively, if you type “What is my IP address” in Google, the results will show your public IP address.
How to find your local internal IP address
In case you need to know your local or private (internal) IP address or if you’re wondering how to find IPv4 address, you can also do so through the Network section in System Preferences. Actually, it’s exactly the same process as looking for your external IP for when you’re connected via an Ethernet cable:
- Open your Mac’s System Preferences
- Click on Network
- Highlight the green-dot option and see the IP in the right pane. It’s likely to have a xxx.xx.xxx.xxx format.
How to find your IP address using Terminal
Just like on a Windows computer, you can use ipconfig on Mac with Terminal to find your local IP address. If you’re connected to the internet through a wireless network:
- Hit ⌘ + Space to search and open Terminal
- Type in ipconfig getifaddr en0
Every device connected to your network including the router is assigned an internal IP address. Together, the entire network is assigned a single external IP address once it’s connected to the internet.
How to hide your IP address with a VPN
Need to protect sensitive data while you’re browsing the internet with public WiFi? You may be wondering how to change IP address on Mac. In this case you need a reliable way to hide your IP address when on the internet, and using a Virtual Private Network or VPN can be a big help, since your IP address will be replaced with one from a Virtual Private Network provider.

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
Lookup Ip Info On Mac
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.

- 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. - CayenneJim6795 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?)
- DatilCrimsonKidA Apr 27, 2018 at 02:04pmGood 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 ?'
- CayenneEd 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!
