How to Find Your IP Address on a Computer

## What is an IP Address? An **IP address** (Internet Protocol address) is a unique string of numbers separated by periods that identifies each computer using the Internet Protocol to communicate over a network. There are two types of IP addresses: - **IPv4**: The most common type, consisting of four numbers separated by periods (e.g., 192.168.1.1) - **IPv6**: A newer version that uses a longer string of numbers and letters (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334) ## Finding Your IP Address on Windows ### Using Command Prompt 1. Press `Windows + R` to open the Run dialog 2. Type `cmd` and press Enter 3. In the Command Prompt, type `ipconfig` and press Enter 4. Look for "IPv4 Address" under your active network adapter ### Using Windows Settings 1. Open Settings (Windows + I) 2. Click on "Network & Internet" 3. Select "Wi-Fi" or "Ethernet" (depending on your connection) 4. Click on your active network connection 5. Scroll down to find your IP address under Properties ## Finding Your IP Address on macOS ### Using System Preferences 1. Click the Apple menu 2. Select "System Preferences" (or "System Settings" in newer versions) 3. Click on "Network" 4. Select your active connection 5. Your IP address will be displayed on the right ### Using Terminal 1. Open Terminal (Applications > Utilities > Terminal) 2. Type `ifconfig` and press Enter 3. Look for the section labeled "en0" or "en1" 4. Your IP address will be listed next to `inet` ## Finding Your IP Address on Linux ### Using Terminal ```bash ip addr ifconfig hostname -I ``` ## External vs. Internal IP Address It's important to distinguish between your **internal** and **external** IP addresses: - **Internal IP Address**: Assigned by your router to devices within your local network - **External IP Address**: Assigned by your Internet Service Provider (ISP) and used to identify your network on the internet ### Common IP Address Patterns * Local IPv4 addresses typically start with: * 192.168.x.x * 10.0.x.x * 172.16.x.x through 172.31.x.x To find your external IP address, you can: * Visit websites like [whatismyip.com](https://www.whatismyip.com/) or [ipchicken.com](https://www.ipchicken.com/) * Use a search engine and type "what is my ip" * Use the command line: ```bash curl ifconfig.me ``` ## Troubleshooting Tips If you can't find your IP address: * Ensure your network connection is active * Try disconnecting and reconnecting to the network * Restart your network adapter * Check if your system has multiple network adapters enabled For more detailed information on IP addresses, you can visit [Wikipedia's IP Address page](https://en.wikipedia.org/wiki/IP_address) or explore [Cisco's Networking Basics](https://www.cisco.com/c/en/us/solutions/small-business/resource-center/networking/networking-basics.html) for a deeper dive into networking concepts.
