Identify Device Through Mac Or IP
The ability to identify a device through its MAC or IP address is essential for network security and control. In this article, we will explore how this task can be performed efficiently and accurately.
How is a device connected to the network identified?
An IP address is a unique identifier used to identify a device on the Internet or on a local network. The term “IP” stands for Internet Protocol, which is a set of rules that determines the format of data sent over the Internet or a local network.
In short, IP addresses are necessary to allow communication between devices on a network. These addresses contain location information and provide devices with access to communication. The Internet needs a way to distinguish between different computers, routers, and websites, and IP addresses serve this function in an essential way.
What is the function of the netstat command?
The netstat command is a tool that provides information about network status and protocol statistics. Allows you to view the status of TCP, SCTP protocols, and UDP endpoints in table format. It also displays information about the routing table and interfaces details.
The netstat command provides different types of network data, depending on the command line option selected. These visualizations are very useful for systems administration. Below is the basic syntax of the netstat command:
This section describes the most commonly used options of the netstat command. For more information on all the available options, see the netstat command man page.

How to locate the location of a cell phone?
If you find your device after you’ve wiped it, you’ll need to use your Google Account password to use it again. Learn about device protection.
In a browser, go to android.com/find.
Access your Google Account.
If you have more than one device, select the lost device at the top of the sidebar.
If your lost device has more than one user profile, sign in with a Google Account that’s in your personal or primary profile. Get information about user profiles.
The lost device will receive a notification.
On the map, you will receive information about the approximate location of the device.
If your device is not found, you may see its last known location if it is available.
If prompted, enable the lock and erase features.
Select what you want to do:
– Play sound: Play your device at maximum volume for 5 minutes, even if it is set to silent or vibrate.
– Lock device: Lock your device with your PIN or password. If you haven’t set a blocking parameter, you can configure it. To help you recover your device, you can add a message or phone number to the lock screen.
– Erase device data: Permanently erase all data on your device, but may not erase the contents of SD cards. After erasing data, Find My Device will stop working on your device.

How do you use the ping command?
The ping command is used by running the command prompt console. This command is also available on Linux and macOS operating systems. Once the console is open, we simply have to write the ping command, followed by a space and the IP address or website we want to consult. Here is an example:
In the image above, you can see the ping response to the Google website and an IP address on the local network, specifically the private IP address of our router. The response displays the following information:
– Bytes: It is the size of the data packet sent.
– Time: It is the time it took to send it and receive a response from the destination host.
– TTL: It is the time to live in each hop it takes until it reaches the host, one is discounted in each hop to prevent the packet from traveling the network infinitely and being discarded when the time comes.
– Packets: Shows the number of packets sent, received and lost.
– Approximate round trip time in milliseconds: Used to know how long the four ping requests made took on average.
Importantly, it is also possible to ping a hostname. In this case, the host name resolves to the destination’s IP address according to the DNS settings of our operating system. The IP address will be displayed in an informational frame of the program, along with ping statistics. If you make a mistake when typing the IP address or host name, you will receive an error message.

How to ping the computer name?
If you need, you can use the Ping command with different options to adapt it to your needs. Below, we present the most important options:
– Option “t”: This option searches for a continuous connection with the selected destination computer until you interrupt the process with CTRL+C. This allows you to see the Ping statistics. This is what is known as infinite Ping.
– “to ip” option: Use the Ping command with this option and the IP address of the destination computer to find out the host name of the destination. The computer name will be displayed along with the Ping statistics on the terminal.
– “n number” option: With this option, you can define the desired number of ICMP echo requests. By default, Ping sends four requests.
– “l size” option: With this option, you can define the size of the ICMP echo request packet in bytes. The standard value is 32, but with Ping you can send data packets of up to 65,527 bytes.
– Option “f”: If you execute the Ping command with this option, the “Do not fragment” flag will be set in the IP header of the echo request packet. This means that the request cannot be divided into smaller units by network nodes on its route to the destination. This option is only available on IPv4 networks.
– “i TTL” option: With this option, you can define a custom TTL for your ICMP echo request. The maximum value is 255.
– Option “4”: This option requires the use of IPv4 and is only used if you address the recipient using the computer name.
– Option “6”: This option requires the use of IPv6 and is only used if you address the recipient using the computer name.
If you need more information about the most important CMD commands or how to apply the Ping command for performance testing, you can consult the basics article on the Windows command prompt and the Digital Guide.
How to make a hidden device visible?
To work around this behavior and see disconnected devices when you click “Show Hidden Devices,” follow these steps depending on your version of Windows:
– For Windows 8 and later, skip to step 3.
– For Windows 7 and earlier, start with step 1.
Step 1: Click “Start,” select “All Programs” or “Programs,” then click “Accessories,” and then “Command Prompt.”
Step 2: At the command prompt, type the following command and press “ENTER”: “set devmgr_show_nonpresent_devices1”.
Step 3: For Windows 8 and later, from “Start” search for “device manager” and select “Device Manager” from the results.
Step 4: For Windows 7 and earlier, type the following command at the command prompt and press “ENTER”: “start devmgmtmsc”.
Step 5: Troubleshoot devices and drivers in Device Manager. Click “Show Hidden Devices” in the “View” menu of Device Manager to see devices that are not connected to your computer.
Step 6: When you are done troubleshooting, close Device Manager. Type “exit” at the command line.
Note: For Windows 7 and earlier, closing the command prompt window will clear the “devmgr_show_nonpresent_devices1” variable that you set in step 2 and prevent ghost devices from being shown when you click “Show hidden devices.” .
If you are a programmer or advanced user and want to be able to see devices not connected to your computer, you can set this environment variable globally by following these additional steps:
– Right-click on “My Computer”.
– Click on “Properties”.
– Click on the “Advanced Options” tab.
– Click on the “Environment Variables” tab.
– Set the variables in the “System variables” box.
Note: Use this method only for troubleshooting or development purposes, or to prevent users from accidentally uninstalling a required device that is not connected to the computer, such as a USB device or docking station that is not connected to a laptop. .
A device identifies itself on the network through its unique IP address. The “ping” command is used to send a data packet to an IP address and check if the device is connected and available. The “netstat” command displays active network connections and information about the ports used. To locate the location of a cell phone, a location service based on the cell tower signal or the device’s GPS can be used. To make a hidden device visible, you can use the “ipconfig” command in Windows to show all devices connected to the network. To ping the computer name, you can use the “ping” command followed by the computer name instead of the IP address. The “ping” command is used to verify network connectivity and latency between two devices.
