How to Delete My IP Addresses
By Mike Benson
The Internet Protocol driver on your computer is responsible for deciphering and storing the incoming address data from the host. The address information can be assigned either automatically from the host's computer or manually on the client's computer. Network providers that do not use Dynamic Host Configuration Protocol (DHCP) servers will require you to configure the IP address information on your devices manually. If you are changing hosts or switching from a static assignment to DHCP, you will need to delete your existing IP address information.
Remove Through Command Prompt
Click "Start" and type "Command" in the search box.
Right-click "Command Prompt" from the search results list and click "Run as Administrator."
Click the "Yes" button on the "Do you want to allow..." dialog box. This loads the Windows Command Prompt on your screen.
Type "ipconfig /release" and press the "Enter" key. This command deletes all IP address information from the driver. If you are on a DHCP network and are interested in obtaining new address information, type "ipconfig /renew" and press "Enter." This command attempts to retrieve a new set of addresses by renewing the DHCP lease.
Remove Through Network and Sharing Center
Press the "Windows" and "R" keys simultaneously on your keyboard.
Type "Control Netconnections" and press the "Enter" key. This opens a new window on your screen containing your network adapters.
Right-click your adapter and click "Properties." This opens a "Properties" dialog window.
Double-click "Internet Protocol Version 4 (TCP/IPv4)" in the "This Connection Uses the Following Items:" section. This loads a dialog box containing your current static IP address information.
Click in the radio buttons next to "Obtain an IP Address Automatically" and "Obtain DNS Server Address Automatically" and click "OK" if you want to switch to DHCP addressing.
If you simply need to apply new IP address information, type the new address information in the appropriate fields and press the "OK" button.
