Windows Ipconfig Command Tutorial With Examples To List, Change, Renew IP Configuration

Open Command Prompt

We can open command prompt in different ways. The easiest way is Start -> Run and type cmd and press enter like following screenshot. Click open will start MD-DOS.

List Current IP Address

We can list current interfaces and their related IP addresses with the ipconfig command like below.

> ipconfig

Release All IP Address

As we see that we have IP address assigned to the interface Local Area Connection. We should first release the IP address with ipconfig /relase . This will release all IP addresses of all interfaces

> ipconfig /release

Release Specific Interface IP Address

In previous example we have released all interfaces all IP addresses. This is not useful if we have multiple interfaces and we only want single interfaces IP address to release. We can specify the interface name to release given interface IP address. In this example we will only release IP address of Local Area Connection . Be warned that the name of the interface should be correct to work properly.

> ipconfig /release "Local Area Connection"

Renew IP Address

In order to get new IP address from DHCP server we should renew our IP address with ipconfig /renew command like below. This will run DHCP mechanism and get new IP address from the DHCP server. But some DHCP servers prefer to provide same IP address for same MAC address.

> ipconfig /renew
