This wikiHow teaches you how to change the public IP address on your computer by power-cycling your router. If you want to change the private IP address (the one assigned to the computer when connecting to the local network), you need to execute the Command Prompt command on Windows or access the network settings on the Mac computer.
Steps
Change public IP address
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/fc/Acquire-a-New-IP-Address-Step-1-Version-4.jpg/v4-728px-Acquire- a-New-IP-Address-Step-1-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/fc/Acquire-a-New-IP- Address-Step-1-Version-4.jpg/v4-728px-Acquire-a-New-IP-Address-Step-1-Version-4.jpg”,”smallWidth”:460,”smallHeight”:344,” bigWidth”:728,”bigHeight”:544,”licensing”:”<div class=”mw-parser-output”></div>”}
Find the device’s current IP address. To know if the last IP address has been changed successfully, you need to know the device’s current IP address.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d1/Acquire-a-New-IP-Address-Step-2-Version-4.jpg/v4-728px-Acquire- a-New-IP-Address-Step-2-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d1/Acquire-a-New-IP- Address-Step-2-Version-4.jpg/v4-728px-Acquire-a-New-IP-Address-Step-2-Version-4.jpg”,”smallWidth”:460,”smallHeight”:344,” bigWidth”:728,”bigHeight”:545,”licensing”:”<div class=”mw-parser-output”></div>”}
Power off the device. This can be the computer, phone, or tablet that you want to change the IP address on.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a6/Acquire-a-New-IP-Address-Step-3-Version-4.jpg/v4-728px-Acquire- a-New-IP-Address-Step-3-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a6/Acquire-a-New-IP- Address-Step-3-Version-4.jpg/v4-728px-Acquire-a-New-IP-Address-Step-3-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Unplug the modem (modem) and router (router) from the Internet and the power source. This process is basically a Wi-Fi reset.
- If the modem and router are integrated 2 in 1, you only need to unplug the entire device.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/4d/Acquire-a-New-IP-Address-Step-4-Version-3.jpg/v4-728px-Acquire- a-New-IP-Address-Step-4-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/4d/Acquire-a-New-IP- Address-Step-4-Version-3.jpg/v4-728px-Acquire-a-New-IP-Address-Step-4-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Wait 5 minutes. This is just enough time for your Internet service provider to allocate a new public IP address to you.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/ca/Acquire-a-New-IP-Address-Step-5-Version-3.jpg/v4-728px-Acquire- a-New-IP-Address-Step-5-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/ca/Acquire-a-New-IP- Address-Step-5-Version-3.jpg/v4-728px-Acquire-a-New-IP-Address-Step-5-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Plug the modem cable back in. The device will start to light up. All lights on the modem must be on or flashing off before you continue.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/14/Acquire-a-New-IP-Address-Step-6-Version-3.jpg/v4-728px-Acquire- a-New-IP-Address-Step-6-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/14/Acquire-a-New-IP- Address-Step-6-Version-3.jpg/v4-728px-Acquire-a-New-IP-Address-Step-6-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Reconnect the router. After a few minutes, the light on the router will also start blinking and then stay on.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/db/Acquire-a-New-IP-Address-Step-7-Version-3.jpg/v4-728px-Acquire- a-New-IP-Address-Step-7-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/db/Acquire-a-New-IP- Address-Step-7-Version-3.jpg/v4-728px-Acquire-a-New-IP-Address-Step-7-Version-3.jpg”,”smallWidth”:460,”smallHeight”:348,” bigWidth”:728,”bigHeight”:550,”licensing”:”<div class=”mw-parser-output”></div>”}
Power on the device. After rebooting, the device will connect to the Internet, but you may need to select and connect to the network manually.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/34/Acquire-a-New-IP-Address-Step-8-Version-3.jpg/v4-728px-Acquire- a-New-IP-Address-Step-8-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/34/Acquire-a-New-IP- Address-Step-8-Version-3.jpg/v4-728px-Acquire-a-New-IP-Address-Step-8-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Open the Internet browser. We will use the usual Internet browser to view the IP address.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/47/Acquire-a-New-IP-Address-Step-9-Version-2.jpg/v4-728px-Acquire- a-New-IP-Address-Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/47/Acquire-a-New-IP- Address-Step-9-Version-2.jpg/v4-728px-Acquire-a-New-IP-Address-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:344,” bigWidth”:728,”bigHeight”:544,”licensing”:”<div class=”mw-parser-output”></div>”}
Type “What is my IP address” into the browser. If the IP address that appears is different from the previous one, you have succeeded.
- If the IP address does not change, you may need to power off the router for a longer time. Try leaving the router off overnight and back on the next morning.
Change private IP address on Windows

Look at the current IP address. The IP address will be to the right of the “IPv4” value; This number sequence corresponds to the current device on the local network.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/48/Acquire-a-New-IP-Address-Step-17.jpg/v4-728px-Acquire-a-New- IP-Address-Step-17.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/48/Acquire-a-New-IP-Address-Step-17.jpg/ v4-728px-Acquire-a-New-IP-Address-Step-17.jpg”,”smallWidth”:460,”smallHeight”:342,”bigWidth”:728,”bigHeight”:542,”licensing”:” <div class=”mw-parser-output”></div>”}

Observe the new IP address to the right of the “IPv4” value. If this number is different from the previous one, you have successfully released and refreshed the device’s internal IP address.
- This process only works if the computer is connected to an Ethernet network with other devices. You won’t be able to change your public IP address using this method.
