Learn How to Find Your PC's IP Address
What Is an IP Address and Why You Might Need to Find It
An IP address is a unique numerical label assigned to every device that connects to the internet. Think of it like a mailing address for your computer — it tells other devices and servers where to send information so it reaches your machine specifically. IP stands for "Internet Protocol," and this address is what makes communication between computers possible across networks.

Your PC's IP address consists of four numbers separated by periods, like 192.168.1.100. Each number can range from 0 to 255. This format is called IPv4, which is the most common type used today. There's also a newer format called IPv6, which uses a longer string of numbers and letters, but most home networks still use IPv4.
You might need to find your PC's IP address for several practical reasons. If you're troubleshooting internet connection problems, your internet service provider or technical support may ask for it. If you're setting up a home network or connecting devices together, you'll need to know your computer's IP address. Some people need it to access their computer remotely from another location, or to set up file sharing between multiple devices. Network administrators frequently need IP addresses to manage workplace computers and ensure everything runs smoothly.
There's an important distinction between two types of IP addresses: public and private. Your public IP address is what websites see when you visit them — it's assigned by your internet service provider and identifies your entire home or office network to the outside world. Your private IP address is used only within your local network at home or work. Most of the time, when someone asks for your IP address, they mean your private IP address.
Practical Takeaway: Before you look for your IP address, determine whether you need your public IP (for external services) or private IP (for home network tasks). This will help you know which method to use and which number to provide.
Finding Your IP Address Using Windows Settings
If you're using a Windows PC, the Settings app provides a straightforward way to locate your private IP address. This method works on Windows 10 and Windows 11, which are the most common versions in use today. The process takes just a few clicks and requires no technical knowledge.

Start by opening your Settings app. You can do this by pressing the Windows key on your keyboard and typing "Settings," then clicking the Settings icon that appears. Alternatively, you can right-click the Start menu button in the lower left corner and select "Settings" from the menu. Once Settings is open, look for the "Network & internet" option in the left sidebar and click it.
Within Network & internet, you'll see several options. Click on "Wi-Fi" if your computer connects to the internet wirelessly, or "Ethernet" if you use a wired connection with a cable. Once you've selected the appropriate connection type, look for the name of your network (called the SSID for Wi-Fi connections). Click on it, and a detailed information panel will appear.
In this panel, scroll down until you find the "IPv4 address" field. The number shown here is your computer's private IP address on your home or office network. You may also see an "IPv6 address" listed below it. Write down or screenshot the IPv4 address — this is the number you'll typically need for network tasks. This number will usually stay the same as long as your computer remains connected to the same network, though it can occasionally change depending on your network's settings.
The Settings method also shows you other useful information, like your subnet mask and default gateway. The subnet mask helps determine which other devices are on your local network, and the default gateway is typically your router. Understanding these numbers can be helpful when troubleshooting network problems.
Practical Takeaway: Write down your IP address along with the date you found it. If you need to troubleshoot connection problems later, having this information documented helps you notice if the address has changed, which can sometimes indicate network configuration issues.
Using the Command Prompt to Check Your IP Address
The Command Prompt is a text-based tool built into Windows that provides direct access to your computer's network information. While it might look intimidating if you've never used it before, finding your IP address this way is actually quite straightforward and takes just seconds.

To open Command Prompt, press the Windows key and type "cmd" without the quotes. You'll see "Command Prompt" appear in the search results. Click on it to open the application. A black window with white text will appear — this is Command Prompt. Don't worry about the technical-looking interface; you only need to type one simple command.
Type the command "ipconfig" and press Enter. Your computer will display a list of network adapters and their associated information. Look for the section labeled "Ethernet adapter" if you use a wired connection, or "Wireless LAN adapter" if you use Wi-Fi. Under the appropriate section, find the line that says "IPv4 Address" followed by a colon and then your IP address.
The output will also show your "Subnet Mask" and "Default Gateway." The Default Gateway is typically your router's address — the device that connects your computer to the internet. This information is useful if you ever need to log into your router to adjust network settings. You might also see "DHCP Enabled: Yes," which means your IP address is automatically assigned by your router and may change over time. If it says "No," your address is manually configured and will remain the same until you change it.
Many people prefer Command Prompt for this task because it's quick and displays all network information in one clear list. If you have multiple network connections (for example, both Wi-Fi and Ethernet), ipconfig will show all of them. This can be helpful if you're trying to figure out which connection type your computer is currently using to connect to the internet.
Practical Takeaway: Save a screenshot or photo of your Command Prompt output showing your IP address, subnet mask, and default gateway. This creates a reference document if you need to troubleshoot network problems or contact technical support.
Finding Your Public IP Address
Your public IP address is different from the private IP address on your home network. This is the address that identifies your computer to the outside internet. Websites record your public IP address when you visit them, and it's also what your internet service provider uses to bill you and track your account. Finding your public IP address requires a different approach than finding your private address.

The simplest method is to visit a website that displays your public IP. These sites exist specifically for this purpose. Popular options include "whatismyipaddress.com," "ipchicken.com," or simply searching "what is my IP" in any search engine. When you visit these sites, they automatically detect and display your public IP address on the page. No setup, registration, or special tools are required — just load the page and read the number displayed.
Your public IP address will look similar to your private address — four numbers separated by periods. However, it typically represents a range of addresses assigned to your internet service provider rather than your specific local network. If you share your internet connection with roommates or family members, everyone in the household shares the same public IP address. Within your home, each device has its own private IP address, but to the outside world, all traffic appears to come from one public IP.
It's worth noting that your public IP address can change over time. This depends on whether your internet service provider assigns you a static IP (stays the same) or dynamic IP (changes periodically, sometimes even daily). Most home internet customers have dynamic IPs. If you need a permanent public address — for instance, to host a service that others access remotely — you may need to contact your internet provider about upgrading to a static IP, which often costs extra.
There are security considerations when sharing your public IP address. Generally, it's safe to tell your internet service provider or a legitimate technical support person. However, be cautious about posting it in public forums or sharing it with unknown parties, as it can theoretically reveal your general location and internet provider to anyone who sees it.
Practical Takeaway: Bookmark one of the IP lookup websites for future reference, or remember how to search for "what is my IP" online. This provides quick access whenever you need to check your public address without navigating through computer settings.
