How to Get a New IP Address

by Steve McDonnell Google

    When you connect your modem to the Internet, your Internet service provider leases an IP address to you for a specified period of time, for example two weeks. Websites that impose limits, such as maximum downloads per hour or one rating per person, often identify you by your IP address. You can create a new identity by forcing your ISP to assign a new IP address to you. If you've just bought or moved your computer or router, reconfigured your home network or had a power outage, you may also need to force your ISP to assign a new address.

    New Public IP Address

    Step 1

    Unplug the power from your DSL or cable modem and router. Disconnect either the telephone or coaxial cable from the modem. Leave both devices disconnected for at least five minutes. Reconnect the cable and the power and turn on the device. Navigate to the modem or router status page to determine if you have a new IP address.

    Step 2

    Navigate to the modem or router status network setup page and click the "Release" or similar button next to the IP address on the screen. Click the "Renew" button to force a new IP address assignment if disconnecting the devices didn't work.

    Step 3

    Leave the devices disconnected and without power overnight if you still can't get a new IP address after disconnecting them for five minutes and renewing the IP address in the router setup.

    Step 4

    Contact your ISP and request a new IP address if you can't force your ISP's server to assign a new address to you.

    New Private IP Address

    Step 1

    Click the Windows Start button and "Run." Type "cmd" in the Run box and press "Enter." Type "ipconfig/release" and press "Enter" at the prompt to release the local IP address assigned to your computer and put it back in the pool of available addresses. Type "ipconfig/renew" and press "Enter" at the prompt to request a new local IP address for your computer.

    Step 2

    Assign a specific address to your computer by clicking "Start | Control Panel | Network and Sharing Center | Change Adapter Settings." Right-click the icon that corresponds to your network connection and choose "Properties." Click to highlight "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties." Click the button next to "Use the following IP address." Enter an IP address, subnet mask and gateway address, click "OK" to save the address and click "OK" again to save the settings.

    Step 3

    Disable and enable your network connector to force a new local IP address. Click "Start | Control Panel | Network and Sharing Center | Change Adapter Settings." Right-click the icon that corresponds to your network connection and click "Disable." Wait a minute, right-click the icon again and click "Enable."

    Tips

    • If you use a router, your external IP address is stored on your router, not on your computer. The IP address on your computer is a local IP address for your home network.
    • If you have a dial-up connection to the Internet, simply disconnect and reconnect to receive a new IP address for your connection.
