Your computer, like any device that connects to the Internet, has an Internet Protocol (IP) address. It is a series of numbers interspersed with decimal points (for example, “188.8.131.52”), and acts as a home address that identifies where other devices can find your computer.
Rarely do you need to know your computer
but if you need it, it’s easy to find (for more details, see our articles on how to find the IP address for Windows or the IP address on a Mac).
Here’s everything you need to know about changing your local and public IP addresses.
How to change your public IP address
No matter what kind of computer you have (Windows or Mac), it’s quite easy to change your public IP address.
Your public IP address is usually set by your Internet Service Provider (ISP) and you cannot choose it yourself. However, you can “coax” it into changing in several ways:
- Change your network or location: Your public IP address will change depending on where and how you connect to the Internet. If you have a phone with LTE, for example, disabling Wi-Fi so that it uses that LTE signal will force it to use a different IP address. You can also connect to another Wi-Fi network.
- Restart your internet modem: When you restart the modem (turn it off, wait two to three minutes, then turn it back on), it will refresh all the IP addresses on the network.
- Connect with a VPN: A VPN (Virtual Private Network) hides your public IP address and connects you to a server in a different location with a different IP address. When using a VPN, you can’t choose the IP address directly, but you can usually choose the geographic region you want to appear from, which will determine the IP addresses the VPN software will use to identify you.
If all else fails, contact your ISP and ask them to change your IP address. They may not be able to do it, but it’s okay to ask.

How to change the local IP address on a mobile device
Like any device connected to the Internet, your phone has its own IP address. If you have a compelling reason to do so, you can also change your phone’s IP address.
For iPhone and Android, you can customize the IP address from the Wi-Fi settings page. For step-by-step details on how to do this, see our articles “How to change the IP address on your iPhone” and “How to change the IP address on an Android phone”.
