Every device connected to a network has an IP address—a unique identifier that allows communication across the internet or within a local network. Whether you're troubleshooting connectivity issues, setting up remote access, or securing your network, knowing how to find your IP address is essential. This guide walks you through the process on any major operating system, explains the difference between public and private addresses, and provides practical tools and insights for everyday use.
Understanding IP Addresses: Public vs. Private
An IP (Internet Protocol) address comes in two primary forms: public and private. The distinction is critical for understanding how devices communicate.
Private IP addresses are used internally within your home or office network. These are assigned by your router and allow devices like laptops, phones, and smart TVs to talk to each other and access the internet. Common private IP ranges include 192.168.x.x, 10.x.x.x, and 172.16.x.x to 172.31.x.x.
Public IP addresses, on the other hand, are assigned by your Internet Service Provider (ISP). This is the address the outside world sees when you browse the web. It's what websites use to send data back to your network.
“Your public IP is like your street address—it tells external services where to deliver information. Your private IP is like your apartment number, used only inside your building.” — David Lin, Network Infrastructure Engineer
How to Find Your Private IP Address
Finding your private IP depends on your operating system. Below are detailed steps for Windows, macOS, and Linux.
On Windows (10 and 11)
- Click the Start menu and select Settings.
- Navigate to Network & Internet > Wi-Fi (or Ethernet if wired).
- Select the network you're connected to.
- Scroll down to view the IPv4 address. This is your private IP.
Alternatively, use Command Prompt:
- Press Win + R, type
cmd, and press Enter. - Type
ipconfigand press Enter. - Look for IPv4 Address under your active connection (e.g., Wi-Fi or Ethernet).
On macOS
- Click the Apple menu and select System Settings (or System Preferences on older versions).
- Go to Network.
- Select your active connection (Wi-Fi or Ethernet) from the left panel.
- Your private IP address appears next to Status or .
For advanced users, open Terminal and type:
ifconfig | grep \"inet \" | grep -v 127.0.0.1
The first result is typically your local IP.
On Linux (Ubuntu/Debian-based)
- Open the terminal.
- Type
ip aorip addr showand press Enter. - Locate your network interface (commonly
wlan0for Wi-Fi oreth0for Ethernet). - Your IP will be listed next to
inet(e.g.,inet 192.168.1.15).
hostname -I in Linux for a quick display of your private IP without extra details.
How to Find Your Public IP Address
Unlike private IPs, your public IP cannot be found through system settings alone. Instead, you must query an external service.
Using a Web Browser
- Open any browser (Chrome, Firefox, Safari, etc.).
- Visit one of these sites:
- The site will automatically display your public IP address at the top of the page.
Using Command Line (All Platforms)
You can also retrieve your public IP using command-line tools:
- Windows (PowerShell):
(Invoke-WebRequest -Uri \"https://api.ipify.org\").Content - macOS/Linux:
curl https://api.ipify.org
These commands contact a remote server that echoes back your public IP.

Real-World Example: Troubleshooting Home Office Connectivity
Sarah works remotely and suddenly loses access to her company’s internal portal. Her IT team asks for her public and private IP addresses to verify her location and network setup.
She opens her MacBook, checks System Settings > Network > Wi-Fi, and finds her private IP: 192.168.0.105. Then, she visits whatismyipaddress.com and sees her public IP is 203.45.87.102. She sends both to IT, who confirm her public IP matches the expected region and notice her private IP is conflicting with another device. They guide her to restart her router, which resolves the conflict and restores access.
This scenario highlights why knowing both types of IP addresses—and how to find them quickly—is crucial for resolving real-world tech issues.
Troubleshooting Tips and Best Practices
Even with the right steps, issues can arise. Here’s how to handle common problems:
- No IP address shown? Restart your network adapter or router. On Windows, try
ipconfig /releasefollowed byipconfig /renew. - Multiple IP addresses? Devices may have IPv4 and IPv6 addresses. Focus on IPv4 unless otherwise specified.
- Public IP changes frequently? Most residential connections use dynamic IPs. For consistent access (e.g., hosting a server), consider a dynamic DNS service.
Quick Checklist: Find Your IP in Under 2 Minutes
Follow this checklist to locate your IP address efficiently:
- ✅ Determine if you need your private (internal network) or public (internet-facing) IP.
- ✅ For private IP:
- Windows: Run
ipconfigin Command Prompt. - macOS: Check Network settings or use
ifconfig. - Linux: Use
ip aorhostname -I.
- Windows: Run
- ✅ For public IP: Visit
https://api.ipify.orgor runcurl https://api.ipify.orgin terminal. - ✅ Verify accuracy by cross-checking with another device on the same network.
- ✅ Record or share the IP as needed for configuration or support.
Frequently Asked Questions
Can two devices have the same private IP address?
No. If two devices on the same network have the same IP, it causes an IP conflict, leading to connection drops or loss of network access. Routers typically prevent this by managing DHCP assignments, but manual misconfigurations can cause conflicts.
Does my public IP reveal my exact location?
Not precisely. Your public IP can indicate your general geographic area (city or region) and ISP, but not your exact street address. However, websites and services can use this data for geo-targeting or security filtering.
Is it safe to share my IP address?
Sharing your public IP occasionally (e.g., with IT support) is generally safe. However, exposing it unnecessarily can make you a target for port scanning or targeted attacks, especially if you're running servers. Avoid posting it publicly on forums or social media.
Take Control of Your Network Identity
Knowing how to locate your IP address is a fundamental digital skill. Whether you're configuring a printer, diagnosing a dropped connection, or setting up a game server, having instant access to your network identifiers saves time and frustration. With the methods outlined here, you can confidently retrieve your IP on any device—no technical degree required.
