Have you ever wondered how to find the IP address of someone’s computer on the same network as you? Or how to determine the number of data in an Excel sheet? Well, you’re in luck because in this article we will discuss some useful tips and tricks that will help you accomplish these tasks.
How to Find IP Address of Another Computer on Same Network
If you’re on the same network as another computer, finding its IP address is easy. The first step is to open the Command Prompt on your computer. You can do this by pressing Win+R on your keyboard and typing “cmd” into the Run box. Press enter to open the command prompt.
Once the command prompt is open, type the following command: “arp -a”. This command will display all the devices connected to the network along with their IP addresses and MAC addresses.
After running the “arp -a” command, you should see a list of all the devices connected to the network, including their IP and MAC addresses. Look for the IP address of the computer you want to find, and note it down for future reference.
How to Find IP Address of Someone Outside Your Network
If you want to find the IP address of someone outside your network, the process is a bit more complicated. There are a few ways to do this, but the most reliable method is to use a service like WhatIsMyIP.
To use WhatIsMyIP, simply go to their website and your IP address will be displayed prominently at the top of the page. From here, you can determine the IP address of someone outside your network by using a technique called port scanning.
Port scanning involves scanning a range of IP addresses on a network to find a specific device. There are many tools available for port scanning, but one of the best and easiest to use is Nmap.
To use Nmap, you first need to download and install it on your computer. Once it’s installed, open the Command Prompt and type the following command: “nmap -p 1-65535 [target IP address]”. Replace [target IP address] with the IP address of the device you want to scan.
Nmap will scan the range of IP addresses on your network and display any open ports on the target device. From here, you can determine the IP address of the target device.
How to Determine the Number of Data in an Excel Sheet
If you’re working with Excel, it’s important to know how to determine the number of data in a sheet. This is useful for a variety of reasons, including determining the size of the sheet and ensuring that your formulas are accurate.
To determine the number of data in an Excel sheet, you can use the “COUNT” function. The COUNT function takes one or more arguments and returns the number of cells in the range that contain numbers.
To use the COUNT function, select the range of cells you want to count, then enter the formula “=COUNT(range)” into a cell where you want the result displayed. The formula will return the number of cells in the range that contain numbers.
How to Find the Password of a Protected Excel File
Protecting an Excel file with a password can be a useful way to prevent unauthorized access to sensitive data. However, if you forget or lose the password, it can be frustrating to try and access the file.
Fortunately, there are tools available that can help you find the password of a protected Excel file. One of the best and easiest to use is PassFab for Excel.
To use PassFab for Excel, first download and install it on your computer. Once it’s installed, open the program and click the “Add” button to add the protected Excel file.
Choose the type of attack you want to use to recover the password, and then click the “Start” button to begin the recovery process. Depending on the complexity of the password, the process could take several minutes to several hours.
