There are private IP addresses, used to provide a way for your devices to communicate with your router and all the other devices in your private network; public IP addresses, used to communicate with the rest of the networked devices around the world especially via the internet; static IP addresses, and dynamic IP addresses implying that they either change or they don’t. Different devices and operating systems require unique steps to find the IP address. Let us take a look at each of these.
In Windows
Your router’s IP address is the Default Gateway in your network connection information on Windows. You can either find it using the Command Prompt or through the Control Panel. In the Command Prompt, you can find it by using the ipconfig command.
Via the Control Panel, click Start, type control panel, and then hit Enter. Find the Network and Internet category, and then click the View network status and tasks link. In the upper right corner of the window, click the name of your network connection.
Within the Ethernet Status window, click the Details button. In the Network Connection Details window, you’ll find your router’s IP address listed as IPv4 Default Gateway.
For macOS and iOS
On a Mac, click the Apple menu on the bar at the top of your screen and select System Preferences, then select the Network icon. Select your network connection and then click the Advanced button at the bottom of the screen. In the Network window, select the TCP/IP tab. Your router’s IP address is listed as Router.
On an iPhone or iPad, go to Settings, then to Wi-Fi, and then tap the name of your Wi-Fi network. You’ll see the router’s IP address listed as Router. Read About: How to change your Router’s Default name and password
