How To Change Your Local IP Address

October 2016

Your Public IP address is what identifies your computer on 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 be periodically updated (Dynamic IP).

Each computer also has a local IP address, which is also referred to as the Private IP address. The local IP is what identifies computers on a local network (behind the same router) and, if necessary, it can be changed in the router's settings (refer to the manual provided with the router or check on the manufacturer's website) or via the Windows Control Panel.

How To Refresh Your IP Address

IP address conflicts occur when two computers present on the same DHCP network share the same IP, but fortunately, there is a simple way to refresh your current IP address(es) in Windows.

Click Start and select the Run command. Type
and press [Enter] to launch the Command Prompt. Type
and press [Enter] to view your current IP address. Next, run the
ipconfig /release
command, followed by
ipconfig /renew
. Windows will then assign a new "random IP" to each of the devices connected to the router (within the allowed IP address range).

How To Change Your Local IP Address

Head to the Control Panel > Network and Sharing Center > Change Adapter Settings > Network Connections. Windows will then display a list of known connections (Ethernet or WiFi). Right-click the desired connection and select Properties from the contextual menu. Navigate to This connection uses the following items > Internet Protocol Version 4 (TCP / IPv4) and then click Properties:

Click Apply > OK.
