This information is crucial for network troubleshooting or for setting up remote connections.
Is there a difference between a public and private IP address?
Yes, there is a significant difference between public and private IP addresses. A public IP address is assigned by your Internet Service Provider (ISP) and is used to identify your network on the internet. It is accessible from anywhere in the world, allowing external devices to communicate with your home or office network. This address can change over time unless you have a static IP assigned by your ISP.
On the other hand, a private IP address is used within your local network and is not visible to external devices. These addresses are typically formatted within specific IP address ranges, such as 10.x.x.x, 172.16.x.x to 172.31.x.x, or 192.168.x.x. Private IP addresses facilitate communication between devices on the same local network while maintaining security from external access.
What should I do if my IP address isn’t displaying?
If your IP address isn’t displaying, the first step is to check your network connection. Ensure that your device is connected to a network, whether it be via Ethernet or Wi-Fi. A disconnected network can result in an inability to retrieve an IP address.

If connectivity isn’t the issue, you may also want to run network diagnostics. On Windows, you can do this by navigating to “Settings” > “Network & Internet” > “Status” and clicking on “Network troubleshooter.” On macOS, you can use the “Network Utility” tool. These diagnostics can help identify and resolve issues that could prevent your device from acquiring an IP address.
Can I change my IP address manually?
Yes, you can change your IP address manually, but the method to do so may vary depending on whether you’re trying to change your public or private IP address. To change your private IP address, you can go into your network settings and manually set a new IP address within the valid range for your subnet. This can be done in the properties of your network connection on both Windows and macOS.
To change your public IP address, however, the process is different. Usually, this involves disconnecting your router from the internet for a brief period, which can sometimes result in your ISP assigning a new public IP address when you reconnect. For a more permanent solution, you may need to contact your ISP directly to request a change. Always be cautious when changing IP settings to avoid connectivity issues.
