This wikiHow teaches you how to change both your public IP address and your private IP address on a Windows computer. Your public IP address is the address that your computer broadcasts to other networks, while your private IP address is your computer's specific address within your own wireless network. Changing either of these may fix connection issues.
Steps
Public IP
-
1Unplug your router and modem. Most service providers assign dynamic IPs, which change from time to time. By disconnecting your modem for a long period of time, you are likely to get a new address assigned to you when you turn it back on.
- You may want to check your current IP address before doing this.
- Simply unplugging the router and modem from the wall will work.
-
2Disable your computer's Wi-Fi. This will prevent it from reconnecting to the router when you plug it back in. To disable Wi-Fi:
- Click in the bottom-right corner of the screen.
- Click Wi-Fi in the pop-up window.

3Wait for five minutes. Some ISPs will assign a new IP address in as little as five minutes; if doing this doesn't work, however, you may need to leave your router unplugged overnight (or for around eight hours).
-
4Plug your router back in. As long as you have a different device (e.g., a phone, a gaming console, or another computer) connected to Wi-Fi, the router and the second device will claim the old IP address.
-
5Re-enable Wi-Fi on your computer. Doing so after the other devices have had a chance to establish their connections will most likely change your computer's public IP address.
- You may want to check your IP address again to make sure it has changed.
-
6Contact your ISP. In some rare cases, you may have a static IP address assigned by your internet service provider. In order to get this changed, you will need to contact their technical support directly. Oftentimes, this can only be changed once.[1]
-
7Use a proxy network. This will display a different IP address for your connection; often, it will be an address from a different part of the country or world. Reliable proxies and VPNs often require monthly subscriptions.
Private IP
Renewing the Address
-

-
2Type command prompt into Start. This will search your computer for the Command Prompt app.
-

-
4Click Run as administrator. This option is at the bottom of the drop-down menu.
- If you aren't an administrator on your current computer, you won't have this option and thus won't be able to renew your computer's IP address.
-
5Click Yes when prompted. Doing so opens Command Prompt.
-
6Type in ipconfig /release and press ↵ Enter. This command "forgets" your current IP address.
-
7Type in ipconfig /renew and press ↵ Enter. This refreshes your IP address. Doing this in and of itself will likely solve some connection issues, though it won't always change your computer's actual IP address.

8Fill in the text boxes. Here's what they mean:
- IP address - Usually, your device's IP address will be "192.168.1.X" (or a similar set of numbers), wherein "X" is specific to your device. Change the "X" value to a number between 1 and 100. Make sure you don't use the same IP address as another device on your network (e.g., your phone).
- Subnet prefix length - This depends on your IP address, but will usually be "255.255.255.X".
- Gateway - This is your router's IP address.
- Preferred DNS - Your preferred DNS address (for example: "208.67.222.222" for the OpenDNS server, or "8.8.8.8" for Google's server).
- Alternate DNS - A secondary DNS address (for example: "208.67.220.220" for the OpenDNS server, or "8.8.4.4" for Google's server).
-
9Click Save. Your new network settings will be saved and applied.
