Hey, folks! Ever wanted to know how to find IP address of your buddy's computer in same local network? Well, you're in luck! Here's a no-fancy, no-sophisticated guide on how to do just that. So, let's dive in, shall we?

Step 1: The Magic Command Prompt

First things first, we need to use trusty Command Prompt. You know, that little window that pops up when you're in trouble (or just want to look cool). Here's how to open it:

1. Hit 'Windows' key on your keyboard.
2. Type 'cmd' in search bar and select 'Command Prompt' from list.
3. And voilà! You're in!

Step 2: The Power of 'arp' Command

Now that we're in Command Prompt, we'll use 'arp' command to find IP addresses. It's like magic, but less flashy and more... practical. Here's what you do:

1. Type arp -a and press Enter. This will show you all IP addresses and ir corresponding MAC addresses on your local network.

求锤得锤。 2. Look for IP address of your friend's computer. It will be listed along with MAC address.

Step 3: The Scary World of IP Addresses

Now, if you're not a tech whiz, IP addresses might as well be written in ancient hieroglyphics. But don't worry, it's not as hard as it looks. An IP address is a set of numbers separated by dots (like 192.168.1.100). The first three numbers are network portion, and last number is host portion.，你我共勉。

So, if you see an IP address like 192.168.1.100, first three numbers (192.168.1) represent network, and last number (100) is host.

Step 4: The MAC Address Mystery

MAC address, you ask? It's like a unique fingerprint for your computer. It's a series of letters and numbers separated by colons or hyphens (like 00:1A:2B:3C:4D:5E). This address is assigned to network interface card (NIC) in your computer.

So, if you want to find out your friend's MAC address, you just need to find ir IP address from list generated by 'arp -a' command.

Step 5: The Router's Role

Now, if you can't find your friend's IP and MAC addresses using Command Prompt, you can always turn to router. Most routers have a web interface where you can see all devices connected to network. Just follow se steps:

1. Open a web browser and type router's IP address (usually 192.168.0.1 or 192.168.1.1) in address bar.
2. Login to router using your credentials.
3. Navigate to 'Status' or 'DHCP Client List' section.
4. Here, you'll see a list of all devices connected to network, along with ir IP and MAC addresses.

Step 6: Using Third-Party Tools

For those who don't like Command Prompt or router interface, re are third-party tools that can help you find IP and MAC addresses of devices on your local network. Tools like Fing, Angry IP Scanner, and Advanced IP Scanner can scan your network and provide detailed information about connected devices.

These tools are great for beginners and advanced users alike. Just download and install tool of your choice, and you'll be able to scan your network and find IP and MAC addresses of all connected devices.

Conclusion

So, re you have it! Now you know how to find IP and MAC addresses of your friends' computers in local network. Wher you use Command Prompt, router interface, or third-party tools, you can now share files, play multiplayer games, or just show off your tech skills. Happy hacking!，别担心...
