To get started, click anywhere in your system tray at the bottom-right of your Chromebook. The first method for finding your IP address requires no more than a quick walk through your Chrome OS settings menu. We’ll cover IP addresses first and then, I’ll show you two ways to find your MAC address. There are a few different ways to find your Chromebook’s IP and MAC addresses. If you work on a secured network and the admin has MAC filtering setup, you will need to provide your MAC address in order to be granted permission to use the network.

This number is generally static on a Chromebook but devices such as Android phones, Windows laptops, and others have the ability to randomize this address for a higher level of security. MAC, or Media Access Contol is a unique identifier assigned to each individual device’s Network Interface Card that is connected to a given network. Because these numbers are unique to location and ISP, your IP address at home will not be the same as the IP address at your office, the local coffee shop, or anywhere else. As there is only a finite amount of IPV4 addresses available, IPV6 has expanded rapidly over the past few years. The newer IPV6 consists of a 128-bit IP address and was created in response to the growing number of IoT and connected devices around the world. If you’ve ever set up a network printer, you’ll likely recognize an IPV4 address. The most common is IPV4 which is a 32-bit identifier that usually appears in the form of four sets of numbers separated by decimals. The unique number is what identifies your devices and their respective connections to the internet or internal networks. Depending on the device and the network provider, the numbers can be static or dynamic. We do not see anything plugged into port Gi1/0/41 so this must be the port we are looking for.IP, or Internet Protocol addresses are unique identifiers assigned to connected devices. I say likely since MAC addresses can be changed programmatically to any value you want on most operating systems (I know Linux can). This will ONLY tell you the likely vendor of the network device.

IEEE is the registration authority that contains a list of manufacturer prefixes. We can verify that with a show cdp neighbor command.įrom this switch we can see there are a few Meraki MR access points plugged into it, and we see our connection back to the core switch. A mac address doesnt identify a specific model of a device, but rather the the likely manufacturer. Again, know the topology of your network to know if this is not another switch uplink. Run the same command as before to look at the mac address table. We have discovered that the device is not plugged into the core switch so we must connect to the next switch in line to find what port it may be plugged into.Ĭonnect to the other switch via putty in the same way we connected to the first. Here we see the local interface port Ten 1/X/X is connected to another switch (which is model WS-C2960X switch) and the port that interconnects the two switches is Gi1/0/49. In this example we found the port plugged into another switch which will likely be the case as end user devices are not likely to be plugged into your main core switch. We could use the command “show cdp neighbor” to find if this port is connected to another switch. This is where knowing your network topology is important. Your device therefore is likely to have two MAC addresses. The address is assigned by the manufacturer, for Ethernet and Wi-Fi cards. This will either give the exact port the device is plugged into or the port of the next switch in line it is plugged into. A Media Access Control (MAC) address is a unique numeric identifier used to distinguish a device from others on a network.

Now show the mac address table of the switch by entering either (depending on the code versions): This will show the mac address of the device. The example below shows searching for IP address 10.1.4.40. Now under wireless card you will see Physical Adress. If it returns no entry, then generate traffic to the IP address by pinging the IP address and rerun the command. Hi, Open command prompt (or powershell) by right-clicking on start and type ipconfig /all. First connect using putty to the core switch of the site that is doing the routing. To find the port you must already have a good understanding of the network topology and have access to the switches CLI.

This blog shows how to do so in a Cisco environment trying to find the IP address 10.1.4.40. It may just be that documentation is being created. There could be a compromised device generating too much traffic in your network. It may be necessary to find which switch port a device is plugged into by using its IP address.
