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.

  1. 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.

  3. 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).
  4. 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.
  5. 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.
  6. 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]
  7. Use 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.

Renewing the Address

  1. This will search your computer for the Command Prompt app.
  2. 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.
  3. Doing so opens Command Prompt.
  4. This command "forgets" your current IP address.
  5. 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.

Changing the Address

  1. This is the first tab on the left pane.
  2. Scroll down to access this section.
  3. Click the dropdown menu from the dialog that appears and choose the "Manual" option.
  4. 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).
  5. Your new network settings will be saved and applied.

    You'll find this ability in the Settings in Windows. Go to your TCP IP Settings, look for ipv4 and specify the static address that you need. For Mac OS, it's the same process but you'll find it under System Preferences under Networking.

    You can use the command prompt (go to start, cmd, enter). Once there, type "ipconfig"; it should show a bunch of stuff. Look for the one that says "default gateway."

    You have to use the MD5# protocol in CMD. That should work if you type that into command prompt.

      Tips

      • You'd change your public IP address in the event that you were kicked out of a gaming service (e.g., Steam), while you'd change your private IP address to fix website loading errors.
      • Using a proxy server will not change your IP address in the traditional sense, but it will alter the IP address that others can see.
      • You can also use a browser like Tor to hide your IP address, though such browsers can be dangerous and are often slower than average.

      • If you choose an in-use IP address for your computer when changing its private IP address, the device that is currently using that address will get kicked off of the network.
