Windows ipconfig Command Tutorial

by

Windows provides the ipconfig command in order to list and manage the network, IP, DNS, DHCP Default Gateway from the command line. ipconfig command provides different options where DHCP configuration can be changed refreshed. The ipconfig command mostly used to list IP, DNS, DHCP, Gateway, or network information and renew the IP address. But we will explain all parameters of the ipconfig command below.

ipconfig Syntax and Parameters

ipconfig command has very simple syntax like below.

ipconfig PARAMETERS
Parameter Description
/all Display all interfaces TCP/IP Configuration
/displaydns Display DNS configuration
/flushdns Flush/Reset DNS configuration
/registerdns Register DNS manually
/release INTERFACE Release IP configuration for the specified INTERFACE
/release6 INTERFACE Release IPv6 configuration for the specified INTERFACE
/renew INTERFACE Renew the INTERFACE IP configuration with DHCP
/renew6 INTERFACE Renew the INTERFACE IPv6 configuration with DHCP
/? Help information

Print ipconfig Command Help Information

Even the ipconfig is simple command we may need to list help information. We will provide the /? parameter which will all parameters and some basic samples about ipconfig.

> ipconfig /?

List IP Configuration

The most popular usecase for the ipconfig is listing the IP configuratin without providing any parameter. This will list information like DNS Suffix, IPv4 and IPv6 address, Subnet Mask and Default Gateway.

> ipconfig
C:\>ipconfig

Ethernet adapter Ethernet0:

   Connection-specific DNS Suffix  . : localdomain
   Link-local IPv6 Address . . . . . : fe80::557b:67:59aa:dcde%7

   Default Gateway . . . . . . . . . : 192.168.142.2

We can also list specific adaptor or interface IP configuration by providing the adaptor name. In the following example we list the adaptor IP configuration named Ethernet0 .

> ipconfig Ethernet0

> ipconfig "Local Network Adaptor"

List All and Detailed Network Configuration

In previous step we have listed basic network and IP configuration. We can display detailed information abut IP, DHCP, DNS, NetBIOS and Ethernet interfaces with the /all parameter.

C:\>ipconfig /all

Release DHCP Assigned IP Configuration

DHCP assigned IP configuration likeIP address, IPv6 address, DNS server, Default gateway can be released and cleared with the /release parameter. We will also provide the interface or adaptor name which is Ethernet0 in this case.

> ipconfig /release Ethernet0

If we just want to release IPv6 configuration we can use the release6 parameter like below.

> ipconfig /release6 Ethernet0

With the following command all interfaces or adaptors starting with the Ethernet will be released.

> ipconfig /release Ethernet*

Renew DHCP Assigned IP Address From DHCP Server

DHCP is used to assign the IP address and provide other network-related configuration to the computers and hosts. We can reset and renew existing DHCP configuration which will reset the assigned IP address and other network configuration like DNS, Default Gateway, Hostname, etc. In order to renew the DHCP assignment, the interface name should be provided the interface names can be listed with the ipconfig command. We will use /renew parameter in order renew the IP configuration of the interface named Ethernet0 . But in some cases, the adaptor or interface can be named as Local Area Connection.

> ipconfig /renew Ethernet0

We can also renew the IPv6 configuration byusing the /renew6 parameter and providing the interface or adaptor name like below.

> ipconfig /renew6 Ethernet0
