Your IP address will typically be listed next to the “inet” label. This is a handy method if you’re comfortable using the command line and can provide detailed network information.
What is the difference between a public and private IP address?
A public IP address is the address assigned to your network device by your Internet Service Provider (ISP), and it is accessible over the internet. This means that any data sent to your device over the internet uses this address for routing. If you’re connecting from home, your router will have a public IP address that represents your entire internal network.
In contrast, a private IP address is used within your local network. Devices such as laptops, tablets, and smartphones in your home network will have a private IP address assigned by your router. This internal address allows devices to communicate with each other without exposing them directly to the internet. Understanding the difference can help you troubleshoot network issues and configure settings appropriately.
What if I have a dynamic IP address? How does it affect my connection?
A dynamic IP address is an address that can change periodically, assigned to your device by your ISP from a pool of available addresses. Most residential internet users have dynamic IP addresses, which can change each time you reconnect to the internet or after a certain period. This means if you try to access services that require a static IP, such as hosting a server, you might face challenges.
However, dynamic IP addresses are perfectly fine for everyday use, such as browsing the internet or streaming content. They offer increased security since the constantly changing address makes it less predictable for potential attackers. If you need a static IP for specific applications, you can usually contact your ISP to request it, though there may be additional costs involved.

Make sure that the IP address is within the range of your local network and does not conflict with other connected devices. After entering the new IP address, click “OK,” followed by “Apply,” to make the changes effective. Keep in mind that improper configurations can lead to network issues, so it’s essential to proceed with caution.
