How to Change Your Local IP Address

Your Public IP address is what identifies your computer when you to connect to the internet. It is assigned by your ISP and depending on the type of service you have subscribed to, your public IP may remain the same (Static IP) or is periodically updated (Dynamic IP). Basically if you want to change your public IP then the only way is to get in touch with your ISP or use a proxy service such as Tuxler or Hotspot Shield to hide/spoof your IP address. 

Each computer also have the local IP address. The local IP which is also referred as Private IP address is used to identify computers on the local network (behind the same router) and it is managed by the operating system. If required, the local IP of a machine can be changed via the router settings (refer to the manual provided with the router or check on the manufacturer's website) or you can change it via the Windows Control Panel.

 to view the current address. Type  ipconfig / release , followed by ipconfig / renew
.
